could you name exactly the demo(s) you refer to? having test cases saves a lot of time

Super Chase HQ indicates we're allowing too many bits of precision somewhere in the Mode 7 code.

MESS SVN is about 15% faster than bsnes for me.

the +1 is only hackish in that a proper fix is probably to special case line 0 to update the y value and "process sprites".

Got my money for the next 2 weeks. Now I need my sleep

r5370 /src/mame/video/snes.c: SNES: Fixed rowscroll line bug in many games

before (Dead Dance (J)):




after:






Oh, the PAL SNES doesn't catch that it must run at 240 vertical resolution...


Ah, ok, so it's not THAT hackish then, just inaccurate

Ah, as a chain reaction the above bug have fixed another weird bug with color windows, examples:

Before:




After:




I love when this happens

I have a suspect about the mode 7 bits... thanks for the test case.

after dinner, if I don't fall asleep (I just traveled by car for around 3 hrs with around 30�C temperature and no air cooling ), I should be able to code a bit and test if I'm correct

stay tuned

Nice, and good luck eta

Dokyusei 2 does a weird thing: during gameplay it swaps between bg modes 1 and 5, presumably for doubling the resolution of the background until a certain line...That explain why it writes both normal and wide sprites versions at the same time too.

Kale, can you investigate the problem that MESS has with Puzzle Bobble / Bust-A-Move, where every other time the bubbles are pushed downward, the sprite positions become desynced from the background layers? I recall that either SNES9x or ZSNES had the same issue until only the past 5-6 years or so.

Mode 1/7 splits are fairly common, especially in sports games. Never heard of a 1/5 before

Super Kick Boxing (J) has severe background graphic glitches, but it's fully playable. Any clues on how to fix that??

I would post some pics here, but I can't find a good free webhosting that allow brazilian IP's...

Keep with the amazing work!
