I could release the disassembled asm for gradius 3 but I’m not really sure what the right way is to release it. Can I release a text file with all of the asm on romhacking.net without getting in trouble or do I need to write a program that rips it out of the game?
I'm pretty sure you can release it here. There are a few complete disassembly documents on the site already. I don't see any for SNES titles yet though, so that could be a first. I did go ahead and get a trace log on some of the lag, and I can see where it happens, but you're probably miles ahead of me if you already have a full disassembly.
Edit: I did a little more research into this. The sprite drawing code does consume a lot of processing time, and I think it is possible to make it run more efficiently. However, that's not the only issue. On the lag trace that I got, the game didn't even reach the sprite drawing routine before it was interrupted by the next NMI. It appears that collision detection is occupying the largest chunk of time, in my test case approximately half of an entire frame.

Good luck with that vram project! It sounds really ambitious :beer:Thanks! I still never tried RetroArch. I guess all the hacking I do eats up all of my free time. :D
I've done a number of side-by-side tests with the Gradius 3 fastrom hack and the improvement is noticeable, though as slidelljohn stated there is still slowdown. However, when combining the hack with an emulator that allows for overclocking (such as the Snes9X 2010 Libretro core for RetroArch), the game is virtually slowdown-free. It's pretty awesome after all these years to play one of the first 16-bit shmups the way it was meant to be played. Gradius 3 is a personal favorite of mine (I prefer the SNES version--that soundtrack is gold), and seeing it running so smooth (also flicker-free using the above emulator) is a real treat.
In the main function if this line ($80/82A2 22 F1 8E 80 JSL $808EF1[$80:8EF1]) is nop'ed reload the cart from the begging and
just let the game play until the ship crashes. It should crash around 2 minutes and 31 seconds. Now if you let the game play
without removing that line the game will crash around 2 minutes and 46 seconds. So just that one line of code eats up 15 seconds.
Not sure if the collision detection is loaded from that line but I recall 2 or 3 sections of code that shows the slowdown.

Maybe it would be a good idea to post your asm code. If enough of us put our ideas together we could
probable optimize the code more.

Do you have any patches that I can use to test and compare with the fastrom mod I did and the improvements darkmoon did?

I could probably put together something that shows you how to change the difficulty for each level if you want.Yes, I would be interested! :)
Awesome! Glad the work you did wasn't lost. The extra rom space is definitely going to help.Please don't abandon your work. An SA-1 hack sounds nice, but it would increase the power requirements for playing on low powered devices at full speed, doesn't play nice on SNES Classic canoe emulator, it's unusable on flash carts not compatible with special chips, etc.
Well, I just found out someone created a sa-1 hack for gradius 3:
https://www.youtube.com/watch?time_continue=152&v=pmJyQiL9wYg (https://www.youtube.com/watch?time_continue=152&v=pmJyQiL9wYg)
Its kinda funny that person started working on it after I posted my stuff about gradius 3.
It makes me not want to release anymore docs until I finish my projects first. It took a
long time to write that assembly doc and the sa-1 stuff I did already. How can I write and
release docs if I have to worry about someone 1uping something that I'm currently working on?
I don't know if I should throw my gradius 3 work in the trash or continue with it. I guess
on the bright side we all now have a sa-1 gradius 3.
@Aaendi @darkmoon2321
You both did some good work optimizing the gradius 3 code and maybe it might be best to try
and get your new optimizations inserted into that new sa-1 hack. The sa-1 hack is definitely
going to be faster than the fastrom hack.
Please don't abandon your work. An SA-1 hack sounds nice, but it would increase the power requirements for playing on low powered devices at full speed, doesn't play nice on SNES Classic canoe emulator, it's unusable on flash carts not compatible with special chips, etc.
Unfortunately I'm probably not going to be doing much more gradius 3 stuff.
Unfortunately I'm probably not going to be doing much more gradius 3 stuff.Oh well, i respect your decision! You could maybe make an official release of your last patch here on romhacking, the work you have done is STILL amazing and perfectly playable.
I mainly starting playing around with gradius 3 so I could learn how to make
a snes game use the sa-1 chip. Vitor Vilela's sa-1 work is really amazing and
hats off to him for everything he has done. sa-1 is the future of snes rom
hacking. I think anyone that was interested in the gradius 3 fastrom hack should
be more interested in Vitor Vilela's gradius 3 sa-1 hack. The sa-1 hack may not
be perfect now due to no slowdowns but the gameplay could be modified to make it
right just like how Vitor Vilela modified the unlock arcade mode button presses.
I'm going to continue learning the sa-1 so I could one day add to the list of
sa-1 hacks. Hopefully Vitor saves mmx for me to do. :laugh:

With all of this stuff that I'm working on for gradius 3 I needed a easy waySo, i pressed start+b at the 1 player screen, but nothing else showed up afterwards, even held it up to the game start point. I tried again pressing and holding b+start in succession, but no dice.
to start at any level so I made a small hack that lets you start at any level.
This patch also includes text files for the changes that I made to create the hack.

I would like to upload this new patch to romhacking.net. Can anyone test it
to make sure that it is working without any bugs? If anyone can confirm that
it works without any bugs I'll upload it.
When you start a new game try holding start + B + A and when the weapon select screen shows up you can release the buttons and it should start you on level 2 after selecting your weapons. Start + B activates the new asm for the stage select but you still need to hold the other buttons as well to choose the level. If you only hold start + B it will load the new asm but since no other buttons are pressed and held it will load level 1. No new screens pop up to choose a level. Holding the correct button combinations is what chooses the level. Hope that gets it working for you. Let me know how that works.Sorry, nothing :-[
Only thing that I can think of for why it isn't working forI am using LunarIPS as usual. Can you give me the CRC32 and MD5 of the patched rom?
you is you might not be patching it correctly. I checked everything
including the link that I posted and it works every time for me.
Here are a few images that might help. I'm using geiger's snes debugger.

It works, no problem. Tried (start + b) +a, got to bubble stage.
niuus, maybe make sure you press a + b, THEN (without releasing a + b) press start?
@niuusSorry for the late reply, finally returned to my computer today. So! It works! The test led me to the Bubble Stage. Does this patch include the optimization or can i just stack it against one of your previous patches? (Optimization only, or SA-1 Optimization)
Did you get it to work yet?
I made it to work on a non modified gradius 3 but I think it should work on theHey! Just a quick heads up:
fastrom hack I made. I don't have a working SA-1 Optimization, vitor does. I don't
think the patch is compatible with vitor's SA-1 Optimization but my source is
included with the patch so anyone could very easily make it compatible with any
gradius 3 hack.
The assembly looks like it was ether written to cause a lot of slowdowns
(which is the most likely thing) or the programmers were not that smart (I don't think
that's why the game slows down so much).
Here is another example of how the assembly throughout the rom was programmed that could
cause slowdown.
This asm is traced from gameplay when a enemy is killed.Code: [Select]$02/8502 F0 01 BEQ $01 [$8505] A:0000 X:0900 Y:DD2A D:0000 DB:01 S:1DE3 P:envmxdIZCHC:1072 VC:017 00 FL:454

Does anyone see whats wrong with this asm? I found 4 different occasions that
this happens and there could be more. This also happens with each of your bullets
when they disappear.

Here's yet another optimization patch.
Wow John, a few years pass and you go from graphics hacking to making mod chips, as well as advancing SNES Emulation in general. Well done. :thumbsup:
Thanks MMR! The patch is getting better thanks to the
optimizations that Aaendi has been doing. I should use my words more carefully so no one gets confused when I say almost equal to or slightly faster than the sa-1 patch. The sa-1 is about 3 times faster than the fastrom so the game definitely isn’t running the code nowhere near as fast as the sa-1. The code is being optimized to use less code that is more efficient than how the original programmers written the code therefore making it appear almost as fast or possibly in the near future slightly faster. Adding new features and more enemies on the screen the sa-1 chip would be the way to go due to the 3x speed over fastrom but there is still a limit to how many enemies/sprites that can be on the screen and per line. If you would like to do optimizations in the parodius game you should look into creating a disassembly file of all of the code in that game. The fastrom patch that I made was created using my disassembled code that I uploaded to romhacking.net. You should look at that file to give you a example of how you could create a file like that for your parodius game. I do plan on creating documents of the before and after of the optimizations that I have worked on so others can use the documents as a example to create optimizations for other games.
No, I do not think that is correct. I think if bit 0 and 1 are not set for $4201 it will activate the second set
You are probably having problems with the multitap because $4201 is for the joypads and you are zeroing out all of the bits. 2 bits are used for the controllers and the other 6 are not used for anything. There are 8 pins on the cpu for each bit for the joypad I/O ports $4201. The last 2 pins I think bit 7 and 8 are connected to the controls and the other 6 are not connected to anything on the motherboard. When you do your testing I think you need to have 128kb vram activated when you activate 256kb. So try only using those 2 bits/I/O ports.
Is the vram viewer capable of displaying both 128kb sets of vram at the same time? If not, can you make it to where it does so I can run a few test?
@slidelljohn
Is it possible to put more code on the same line as the original code using asar? or have to expand the rom?
So this is a Super SNES-ROM-ROM upgrade? ;DUm...yea ::)
@slidelljohnI’m sure there are more than a few things causing the slowdown on stage 3. The stars are both on a background layer and on the sprite layer. The stars that are on the sprite
why is underground stage 3 so slow? And why do the stars still stay on BG using 30 sprites? is it possible to remove?
Um...yea ::)I was making a joke about it being like a Turbo Super CD upgrade. :)
https://www.mediafire.com/file/8az4jdz3ajxlf6s/Gradius_III_optimization.ips/fileHi Aaendi. Would i need this only patch to get the best, or does it need to be stacked against all the previous patches, or slideljohn's?
I had the idea of making the game check to see how many scanlines it has left, and if it ends only a couple lines too late it allows itself to start the next frame late so there is a bit of leeway before it starts slowing down. Unfortunately there is some force blank flickering while paused as a result.
EDIT:
I got rid of the forced blanking while paused by not letting the sprite processing code start until active display.
