Welcome To My Projects Page!
I currently have 2 important projects that need to be finished and released.
Project #1 Gradius 3 (fast rom about 99% complete, sram support work in progress)
I have a near complete Gradius 3 fast rom. All assembly is complete there is just some data that still needs
to be changed to fast rom locations but it shouldn't really affect the speed much. There is definitely a noticeable
amount of decreased slowdowns but it still doesn't remove all slowdowns. Here is the patch:
http://www.mediafire.com/file/cg9yg9tpce03ytk/Gradius_III_%2528U%2529_%255B%2521%255D_%257BFast_Rom%257D.rar/fileI also added extra difficulties that you can unlock by holding L, R, Y, and B buttons at the same time when you go into the
option menu. There are 4 new difficulties which are elite, master, expert and pro. Normal, hard and arcade are slightly easier.
Elite difficulty is the same as the original arcade difficulty but master, expert, and pro are gradually harder with pro as the
hardest.
The lastdual helped me with this patch by checking for bugs that I might have missed. There could still be some bugs so let me
know if you find any. I really need someone to try and beat the hardest level to see if there are any bugs in the gameplay.
My main goal for gradius 3 is to remove all slowdown, add sram and make it feel like a competition cart. I also want to add
a new system for calculating your score after each boss kind of similar to super punch out. Now fast rom will never remove all
of the slowdowns so I have been learning about the sa-1 chip. I do have a gradius 3 rom that is updated to use the sa-1 chip but it
does not load gradius 3's assembly yet. I have been gradually changing the assembly code to store all wram data into bw-ram for
the sa-1 chip to work properly, this is near complete. When I complete the wram to bw-ram change I'll start working on getting
the sa-1 to load most of the assembly. I plan on having the snes cpu live in wram so the cpu's don't collide so I can get the full
speed out of the sa-1 chip. I have no clue how long this is going to take but I chose gradius 3 for this because it is a small rom.
I hope everyone enjoys the fast rom patch and the extra difficulties.
Project #2 New snes mod chip called Super V-Power! (v = vram) (100% working but could still be improved)
This mod chip is for adding extra vram to the snes. The snes has 64kb of vram but the ppu is capable of using 128kb of vram.
Creating this mod chip kind of just fell in my lap. I did not figure out the ppu can use the extra vram and I'm not really sure who
did but byuu made higan v1.00 and up capable of using the extra vram because he said it should be possible. You can see how I ended
up creating this mod chip on byuu's forum. Byuu's forum is gone but it has been completely archived here:
http://helmet.kafuka.org/byuubackup2/viewtopic.php@f=16&t=1559.htmlAll of the mod chip stuff is at the end of that page but you can see how it ended up getting made from reading everything from the
beginning. I also modified a snes debugger to show the extra vram in the vram viewer so there is a debugger that's supports the extra
graphics. The link to the debugger is on that 1st page. Qwertymodo was a really big help in showing me how to create the castellated
holes to mount the pcb to the snes and he helped me in how/who to send the pcb to to get made. The entire pcb I designed myself and
created in eagle cad. Im getting ready to create a updated version of the super v-power mod chip and when its finished I'll upload
all of my schematics. Im not interested in making any money off of the mod chip it will be fully open source for anyone to make it if
they want to. I do have a few mod chips that Im willing to give away for free to people that have the skills and want to create hacks
that use the extra vram. If anyone has a fully working level editor for a snes game and would like to add this feature to their editor
I would be willing to modify the game that uses their editor to use the 128kb of vram. I already have a mmx v1.1 rom that fully supports
the extra vram but I need to write a editor from scratch to be able to use it. As far as all my searching online I am the only person
to try and get 128kb of vram to work on the snes. I was trying to get analog to get their super nt to support the extra vram but I
didn't have any luck probably because nothing uses the extra vram yet. One day they might add support for it.
Here is my mod chip installed on the snes motherboard:
If I can get the sa-1 hack completed it would set me up for a project that will blow all other projects that I have worked on away,
which is, mega man x with sa-1, 128kb vram and a new engine to have game play like super metroid.
Moderators:
Hopefully it was/is ok for me to talk about this chip here because it could be a game changer for future snes rom hacks. If I broke any
rules let me know and it wont happen again and I'll delete the Project #2 post.
