Home Page Forums MAME MAME The SNES WIP topic

You can find a proper bug-list updated to rev. 7670 at this link

http://mess.redump.net/sysinfo:snes:bugs

This should make possible updating the page when new bugs are found or old bugs are fixed. In particular, Tafoid is running a whole testsuit and this will help to identify all the games which freezes completely MESS

Notice that I removed games previously listed as broken and which now actually work, but they might well have graphics bugs or other issues worth reporting, so keep testing
Thanks to algrun for testing some of the issues posted by Kale.

Finally, I separated the games not working due to unemulated chips from the ones due to buggy emulation: the former are expected not to work, the latter might get fixed

There are a few issues which I was unable to trigger/reproduce
* Act Raiser (U) (hangs after selecting a stage)
* Bishoujo Wrestler Retsuden: Exhibition wrestler select screen has a one-line bug with some elements (which elements?)
* Final Fight 2 (when the screen scrolls vertically, missing black masking)
* Fushigi no Dungeon 2: the score table has incorrect graphics (when it is displayed?)
* Ikari no Yousai (J) (garbage after beating the first boss, known to happen on a SNES PAL with JP cartridge too)
* Super Mario World: stage 1 boss background is (still) broken, uses mode 7 (this had been reported as fixed at MW... could anyone provide a .inp? it's painful to play this until the boss with an eeepc barely able to go at 60% and the keyboard);
* Puzzle Bobble / Bust-A-Move: Sprites goes offset after some time in challenge mode (sprite seems fine... it's only bubbles which sometimes move, as I reported in the linked page, or is there anything else wrong with this?)
* Tiny Toon Adventures - Buster Busts Loose (U): At the end of the first level, you get a chance to play a mini-game selectable from a spinning wheel. This wheel still show correctly at times, but not all the time. I notice if I fast forward - it seems to show correctly all the time.

could anyone help me e.g. by posting a .inp file or at least a snap with the problem? thanks

I was playing Star Fox (U) last night with the latest svn build at Bobz. In the Asteroid level where you go inside some ships and destroy their core, when you exited the ships the space background was red and garbled instead of black space with stars.

Everything else looked great!

i got it now i was using v1.1 of the game wich plays as i said v1.0 freezes,it's not really like it freeze, you get an image of a girl and then some dots appear over the image, if you press the arrow buttons you can move the image as some puzzle,but definitely its not what it should be showing

Edit: i'll try to give some .inp files too for some of the games you posted

@Tafoid thanks for letting me know

Just a FYI, I sent ETA this .INP already:

* Tiny Toon Adventures - Buster Busts Loose (U): At the end of the first level, you get a chance to play a mini-game selectable from a spinning wheel. This wheel still show correctly at times, but not all the time. I notice if I fast forward - it seems to show correctly all the time.

Gentlemen, behold!


A.S.P. Air Strike Patrol.

The game uses mid-scanline writes to the display brightness register to simulate a shadow for your plane. Only way to emulate this is with a full, true cycle-based S-PPU1+2 emulator.

Any takers?

that's awesome ;-) nothing new to people who have done c64 / speccy emulation I guess.. but it's really pushing things on a console.

There were a couple of NES games that were notorious for mid-scanline PPU twiddling (pretty much anything by Codemasters) but until now it was unknown on SNES. Nice work, byuu.

Thanks, FitzRoy spotted it in-game. The most insidious part is that an emulator would never even know about it. They wouldn't see the shadow line and would think the game was perfect. Hence why I mentioned it here

This game just so happened to hit right between the exact point where I render the scanline, so my entire scanline ended up darkened, making it stand out big-time.

You guys probably also know about Uniracers, but if not ... that one writes to OAM during Hblank in 2-player mode. The S-PPU is controlling the OAM address at this time, and the last fetched sprite data is where the write ends up going. But that one's a lot easier to deal with since it writes during Hblank where the position is stable.

Uhm:

Elfaria 2 (J) doesn't work
SimAnt works
Kishin Douji Zenki - Rettou Raiden doesn't work
Super James Pond works
Super Mario Kart (J) doesn't work

... I had a list and tested a bunch of them (and yes, they weren't working on my machine at the time of the revision). If they works now, ok, fine, but by working I don't mean "black screen" :P

#Ghost Chaser Densei - gfxs glitches during gameplay (e.g. below the status bar) <- again, timing bug
#Puzzle Bobble / Bust-A-Move: Sprites goes offset after some time in challenge mode (sprite seems fine� it's only bubbles which sometimes move, as I reported above, or is there anything else wrong with this?) <- left-over, you can remove this.

(will follow inps for some of the issues)

great, reminds me of gameboy...
