no$gba emulator author wants our help!

what kind of bug reports does he want, individual gamme bugs or general emulator bugs?

I had him to go to Lowlines compat list but he is on DialUp so the flash plugin scared him away, we could have a plain TXT file with the compat results to send him for the nature of this board with pictures and all scared him away also.

I got no time to assemble it, my kid is kinda sick, if you do it, you are free to email him the results and if you don´t want to, i´ll do it.

OK, I'll try to test some homebrew and other stuff, I think I saw some rom-crashes recently. Oh yeah, one little thing to work on is SOUND emulation . Desmume somehow has got it right. Also crashes could print out some error codes, or write debug info - it would be much easier to find bugs then. Automatical backup memory type selection would be nice also. FAT emulation for homebrew would be great addittion for developers.
Enough with the feature requests, on to testing.

Problems with games:

0830 - Picross DS (J) - rom-image crash after selecting input type.


DS Download Demos (only those with issues are listed):

Mario vs Donkey kong 2: March of the Minis - works, transparent gfx.
Elite Beat Agents - missing top/bottom screen, no bottom background in how-to, hangs before game.
Brain Age Train Your Brain in Minutes a Day! - black screen.
Big Brain Academy - works minor gfx errors (black buttons).
Magnetica - works, minor graphics errors (transparent msg box and marbles in top screen intro).
Metroid Prime Hunters - works, slow, problems with menu.
True Swing Golf - menu only, minor gfx errors (some transparent images on top screen), hangs before ingame.
Mario Kart DS Demo - "rom image has crashed".
Pokémon Trozei Demo - works, minor gfx errors (some transparent graphics).
Meteos Demo - works, gfx errors (some graphics are missing, blocks sprites are transparent).
Submarine Tech Demo - freezes right after start.
Table Hockey Tech Demo - works, gfx error (sparks effect when paddle hits the ball).
Zelda Preview Trailer - blank screen, but it seems that demo is running.
Famicom Wars demo - works, gfx errors (main map sprites are cut off).
Ganbare Goemon demo - works, gfx errors (menu top screen missing background, ingame missing 2D backdrop).
Jump Super Stars demo - works, gfx errors (main menu bottom screen background missing, ingame some transparent sprites and message boxes).
Trauma Center: Under the Knife - works, stucks on screen before operation.
Castlevania Portrait of Ruin clip - bottom screen black, audio plays.
Cooking Mama demo - works, gfx errors (no background on bottom screen), slow.
Eragon demo - hangs after starting game.
Tomb Raider Legend demo - black screen after choosing language.

Comparing to earlier version the compatibility has increased, no degradations found (except the submarine tech demo - now splash screen doesn't show up) while testing demos. Still one of more noticable problems is blending (some images are transparent).


Emulator bugs:
* after saving settings with selected NDS Cartridge Backup Media FLASH 512KBytes, no$gba won't start next time, giving unexpected error. (To fix it now you need to remove the line with "FLASH 512KBytes" entry in NO$GBA.ini). Same problem with "FLASH 256KBytes".
* Screenshot (PrintScreen button) causes crash.
* Loading saved state doesn't work right.

I've found a solution to the bug where background doesn't show up, like in Ganbare Goemon and Elite Beat Agents demos and maybe some others. In "Emulation Setup" options select "Allow 3D Rear Alpha" to "yes". As it is marked untested, some new problems might turn up. I had no problems while using it yet.

Here's the updated list from above, fully working demos have been removed:
Mario vs Donkey kong 2: March of the Minis - works, transparent gfx.
Elite Beat Agents - hangs before game.
Brain Age Train Your Brain in Minutes a Day! - black screen.
Magnetica - works, minor graphics errors (transparent msg box and marbles in top screen intro).
Metroid Prime Hunters - works, slow, problems with menu.
True Swing Golf - menu only, minor gfx errors (some transparent images on top screen), hangs before ingame.
Mario Kart DS Demo - "rom image has crashed".
Pokémon Trozei Demo - works, minor gfx errors (some transparent graphics).
Meteos Demo - works, gfx errors (some graphics are missing, blocks sprites are transparent).
Submarine Tech Demo - freezes right after start.
Table Hockey Tech Demo - works, gfx error (sparks effect when paddle hits the ball).
Zelda Preview Trailer - blank screen, but it seems that demo is running.
Ganbare Goemon demo - works, problem with 3D lighting(?).
Jump Super Stars demo - works, gfx errors (ingame some sprites and message boxes are transparent).
Trauma Center: Under the Knife - stucks on screen before operation.
Castlevania Portrait of Ruin clip - bottom screen black, audio plays.
Eragon demo - hangs after starting game.
Tomb Raider Legend demo - black screen after choosing language.


EDIT: While testing these demos again I remembered one more feature which would be nice to have - a bigger distance between screens, like in real NDS.

Sorry, I must've missed that somehow...

Hope I'm about to late. Here are some test results
Spiderman 2 -- the emulator crashes when going into the first stage (unexpected error )
ultimate Spiderman -- the emulator crashes in the middle of the intro(unexpected error)
Spiderman: Battle for New York -- the emulator crashes in the middle of the intro (unexpected error)

I tried these as well
Hotel dusk room 215 -- the ROM image has crashed (this is with encrypted ROM file)
InuYasha secret of the divine jewel -- the game freezes in the middle of intro (the emulator does not crash)

And I thought these might help too...
X-Men the official game -- the game freezes when going into the first stage
Avatar to last air bender -- the game freezes when going into the first stage
Superman returns -- the game freezes when selecting Superman symbols before going into first stage
Pok幦on diamond and Perl -- the game freezes showing the company logo
thanks a lot rockmangames for relaying the information

I will take note. Thanks
