Jumpin' Derby (Japan) (109c)
https://www.sendspace.com/file/p747dj

Try new theory.

Also been discovered that all sa-1 games do not enable fastrom. So real hardware mapper must be slowrom only then. Which bites for (hirom) optimization projects.

Ikari no Yousai (Japan) (0000)
https://www.sendspace.com/file/7ljtjb

Test post-boss1 cutscene. Too much vram transfer during vblank + active draw.
(real hardware blocks vram writes during V:000 draw = avoids glitch)

0x8FC400->0x2118 Bytes:8000 (inc) V:229 VRAM: 4800 (1,0) word
(should be $1000 nt bytes)

Seems like its fixed.

Can you also try the USA one (Operation Logic Bomb) and see if it has the same glitches as the Japan version?

The USA version is fine, that cutscene looks like the Japan one with Sluffy's patch.

Great, thanks!

Please upload savestate of Jumpin' Derby (109c) at title screen. kitpsin pointed out that sram has copy of bg1 nametable. And asking for Kirby 3 savestate at boss6 crash.

SupaSAIAN · « **Reply #2588 on:** May 17, 2018, 11:51:33 am »

Jumpin' Derby savestate with patched or clean ROM??

sluffy · « **Reply #2589 on:** May 17, 2018, 11:53:42 am »

Let's do clean Jumpin Derby rom.

SupaSAIAN · « **Reply #2590 on:** May 17, 2018, 12:02:14 pm »

Here you have for Jumpin' Derby, with Kirby 3 savestate I'm sorry but I can't help you:

Thanks! No problems about Kirby 3, there's others who'll likely fill the request.

Gambling Houraki = funny weird random crashes. Like Accele Brid in similar ways.

Jumpin Derby = has (00)INTENDO label in front. So not being written to correctly on sa-1 side.
(this savestate is very helpful)

Check for random crashes after rolling dice. jsr 03:6000 OpenBus = rts (Accele Brid).

I have been playing during 10 or 15 minutes without crashes, for me the game now is fine.

Hope this one will help you ^^ : https://www.sendspace.com/file/toxspr

Done with vanilla game (9C10), 2 suspend points inside : First Save, when boss 6 has just one red line of live in its second form, and Second Save when the game is freezed after have defeated it. (after freezing, notice that the game is now corrupted and you won't be able to boot it if you come back to the main menu of the SNESC and then try to launch the game : only work with an older save state or if you use rewind function to come back before freezing)

That's actually an interesting Kirby 3 detail. We're looking at Lufia 2 but so far another misty day.

Try adding bg3 to mask window2. Color mask isn't working on Canoe?

Erim fight - Devastation Wave. Load state before special effect should be safe.

I haven't programmed anything since class in college but was able to find the presets in the code for Canoe and looks like there is only the 5 presets that enable hires 10B2, 1016, 10B0, 10F6, 111E which just reinforces what we already know. I barely have any idea what I'm looking at but was able to figure that much out.

lufia2_2.ips + 1016 = No change unfortunately.

Special attacks still just full-screen the effect instead of "expanding/contracting spotlight".

I'll upload a Canoe Suspend Point right before the Erim fight for other testers.
