Home Page Forums MAME MAME The SNES WIP topic

I'll let you know a lot of old/new issues *if* you give me the time, I'm just working on that.

EDIT: this?



;D

EDIT2: there was another (J) game with copy protection check ... that I've forgot the name ... I'll tell you shortly when I get to that part on the topic.

cool. now that I fixed this problem and I moved PPU registers to ppu code [1], I don't plan to change that much the code, so is all yours.

eventually, I will finish the conversion to a video device, but not immediately...


[1] where they should have been since the beginning: they only influence PPU variables and they even use different open bus sources than the main CPU...


EDIT: Super Metroid is fine with rev.7669 :P
and I recalled a nicer protection warning, but my memory could be at fault...


EDIT2: thanks for testing. good night

Ah, you fixed Fushigi no Dungeon 2 ranking screen, I really appreciate that ^^U



EDIT: the game is Deae Tonosama Appare Ichiban (J), and it looks fixed. Oddly, my current compile has non-working inputs ... I'll recompile and let you know.

EDIT2: it's just the screwed compile.

Here's the new & improved bug list, if there's anything not listed there, just let us know on this topic, thanks in advance:

*3x3 Eyes - Seima Korin Den (J): jumps at 8128, shouldn't according to bsnes;

*Accelebrid: hangs soon after the two drones exits from the screen, due of a flaw in its code it jumps to 8260d2 that is reserved address. It probably needs open bus DIRECTLY supported by the CPU core.

*Aging Cassette: errors on EXT LATCH, OBJ L OVER and APU (55)

*Bishoujo Janshi SuchiePai: mode 5 girls are still offsetted to the left (iirc even more than before?)

*Bishoujo Wrestler Retsuden: Exhibition wrestler select screen has a one-line bug with some elements

*Clay Fighter: sound part is bugged;

*Daffy Duck: The Marvin Missions: scroll flicker that isn't caused by timings, heretical_one says hirq?

*Desert Fighter (J): timing issue, the "mission no.1" screen displays after too much time.

*Energy Breaker: World Map is entirely missing (untested, needs somebody capable of playing this);

*F-1 Grand Prix Part 3 / Desert Fighter (J): heavy flicker during (ironically) the briefing for both games, probably abuses the gfx mode changes and the window / blending capabilities (at least mode 7 + something else)
\- Super Offroad the Baja: flickers during gameplay, switches between modes 1 & 7, related to the F-1 GP Part 3 issue of above

*Full Throttle Racing: glitch with the USA map, it displays cutted in half.

*Moryo Senki Madara 2: gap in the text? vshift bug maybe? (H)DMA?

*Puzzle Bobble / Bust-A-Move: Sprites goes offset after some time in challenge mode.

*SNES Test Program: fails "Electronic Test" / one item in Character Test is wrongly displayed (OPT Mode)

*Strike Gunner there's a "bug when the first boss flies past you" (untested)

*Super Drift Out: SRAM doesn't initialize properly, all times are 0'00"00

*Super Mario World: stage 1 boss background is (still) broken, uses mode 7;

*Super Moero Pro Yakyu: a bug with windows causes corrupted tiles during gameplay. At the time I'm writing, it also fails on a copy protection check.

*Super Soccer / BlazeOn: Screen is dimmed on the team selection screen / Atlus logo, could be a timing issue, but it probably isn't.

*Super Tetris 2 & Bombliss Limited (J): keeps showing the BPS logo, fails copy protection check?

*Super Tetris 3: fails copy protection check

*Super Tramp Collection (J): crashes for some reason (open bus?)

*Tokimeki Memorial: Missing text during gameplay?

*Toy Story: After beating the first boss, the stars that falls from the enemy aren't shown (untested)

*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. (untested)

*Wordtris: Controls stops working as soon as the menu screen appears

*Yoshi's Island (J): doesn't start at all now?

This demo just shows junk for two of the screens ("Dutch Viper" before the spinning balls and "The End") as compared with bsnes.

As of r7670, Fushigi no Dungeon 2 doesn't display the proper ranking screen again, is it due of the new fix or it worked by chance? --"

*Strike Gunner there's a "bug when the first boss flies past you" (untested)

there was but fixed in yesterday bobz build

Energy Breaker: World Map is entirely missing (untested, needs somebody capable of playing this)

works for me in r7666, unless i'm looking at the wrong map
same in yesterday bobz build but yet again i could be lookin at the wrong map

*Moryo Senki Madara 2: gap in the text?

yup there is a gap in the text in r7666 doesn't happen in bsnes
ther's still the gap in yesterday bobz build

Super Tramp Collection (J): crashes for some reason (open bus?)

black screen in r7666
also black screen in yesterday bob build
i didn't get a crash

Tokimeki Memorial: Missing text during gameplay?

on menus and name selection and stuff (i guess) the text is missing and when the game really starts most of the graphics are missing in r7666
same for menus but when the game starts the graphics missing before are shown and those shown before are missing and a line in the middle of the screen that shoudn't be there in yesterday bobz build

*Toy Story: After beating the first boss, the stars that falls from the enemy aren't shown (untested)

it doesn't show any stars at all in r7666
same in yesterday bobz build

@Kale: you can add that Rudra no Hihou has problem when the text windows appear and that R-Type 3 graphics get garbled in the second intro loop

OTOH Captain Commando (J) works now, I tried it yesterday. Yoshi's Island works as well in 7670 (even if with huge graphics issues) but you have to use snessfx because it's a Super FX game.

A couple of question tough:

*SNES Test Program: fails "Electronic Test" / one item in Character Test is wrongly displayed (OPT Mode)

which one? It seems the same as bsnes to me...

and how can I reach that Fushigi no Dungeon 2 score table?

@algrun: where did Tokimeki changed compared to past revisions? it works exactly the same as it did for me (svn 7670), and it keeps freezing as soon as I select anything in game (as it has always done)


I'm going to slowly test other issues today. I expect all the protection screens not to appear anymore...


EDIT: overall, I think timing issues (and possibly a bunch of bugs in the CPU opcodes?) might very well lead SNES to enable/disable in the wrong way layers and window masks and hoffs//voffs, producing some of the issues reported. also, we currently don't stop DMA if an HDMA starts in the same channel (which can break things, in principle) and this requires better timing as well to be implemented.

otoh, graphic effects and priorities seem pretty well emulated at this stage (you can compare our implementation of some effects with the snaps posted at http://board.zsnes.com/phpBB2/viewtopic.php?p=201064#201064 and you will see that our code is quite good), and it would be nice to rule out timing in the bugs above to see which problems still exist in the video code.

Kale, but did you simply copy and pasted the old list from August?!? tons of what you listed has been fixed for months...

e.g. Elfaria 2, SimAnt, Kishin Douji Zenki - Rettou Raiden, Super James Pond, Super Mario Kart, all the DSP1 games, and probably many more

you could have said you haven't tested any more the games in these lists...

plus, your list contains titles like Kirby Super Star which cannot work because SA-1 add-on CPU is not emulated.

I guess I'll have to rewrite the whole list later today

Don't forget to add Super Punch-Out to the list. There are issues displaying the KO countdown timer as per my previous post.
