Homebrew Emulation GameYob, a gameboy emulator for DS

[avenir]

That's would be the best option. Will it be made?
Anyway, xxx.frontend2assoc.nds is a good solution for abandoned homebrew IMHO meantime.

Here it is: http://sourceforge.net/projects/lactlib/files/nds/frontend2assoc.7z

Write /__rpg/associations.ini as mentioned in http://gbatemp.net/threads/gameyob-a-gameboy-emulator-for-ds.343407/page-16#post-4588074
Then put frontend2assoc.nds as gbc.frontend2assoc.nds or configure iMenu to call it.
frontend2assoc.nds supports extlink.dat/plgargs.dat/loadfile.dat formats.

By the way, this is just a subset of xenofile, which can understand both associations.ini and extlink...

Many thanks for that little tool for easy MS2-modern menu integration.

Drenn, maybe you can add rumble support in one of next versions of gameyob?

Good news everyone! After some more optimizing I finally seem to have beaten Lameboy in terms of speed. Frolicking around the fields in Shantae, speed would hover from 56-60 FPS, depending on how many objects are on the screen. Which is better than lameboy by at least 5 or 6 FPS!

I'll put it on my list. I don't currently own rumble hardware though.

I own some rumble hardware, but I'll have to test if it still works.
It's an EZ Flash 3in1, I can't seem to get it to register any more though.

Anyhow actually I tried out Shantae and it's running suppose, it's so close to full speed I can't really notice the slow-down!
There issues popped up though.
First was that Shantae herself on the File Select screen had minor graphical glitches during the screen transition in, just a few tiles looking off.
Second was that music started to play incorrectly during the boss battle, the first one on Risky's pirate ship after the burning town stage.

Other than that it handled great, it even took care of the intro stage's colour changes no problem, kudos!

Siiiiick, how far down the to-do list is image scaling? I'm throwing Lameboy away completely the second that gets done.

Lufia - The Legend Returns,Azure Dreams=not work white screen
God Medicine: Fantasy Sekai no Tanjou 30-36 = fps

Hmm... I stopped getting alerts about this thread for some reason, even though I'm watching it. Oh well...

Beating Lameboy in speed? Now that's a good optimisation, rivalling my first set Who would have thought that a const u8[] for opcode cycles could slow things down so much, huh?

 

[LWares87]

I've noticed that Alleyway and Super Mario Land (v1.0) & (v1.1) come up with a 'guru meditation' error on the R4DS (via Wood), but with R4DS SDHC Upgrade they work fine. :/

Removing the op cycles arrays wasn't the main factor. That might have saved me half an fps. The real trick with Shantae was to check for repetitive writes to vram to avoid redrawing the same tile over and over, that saved at least 4 FPS. But only for that game. Then my optimizations to interrupt handling and pc reads also saved another 4 or 5 FPS in total.

It's probably about pickiness for out-of-bounds memory access... I just tried fixing this, let me know if it still crashes or not.

This will come with the new, more accurate graphics engine. It's probably going to be slower, so it won't be in the next official release.

is the recent build available to download now from dropbox?

Yes, most of the time when I push an update to github the Dropbox binary is updated as well. You can download it from the latest build link in the first post.

 

[LWares87]

Ah, ok then.

Anyway... both games, Alleyway (JUE) [!].gb & Super Mario Land (JUE) (v1.1) [!].gb still give 'guru meditiation' errors when using R4DS (via WoodR4). I haven't tried v1.0, but it most probabally does the same.

Can you tell me the value of "pc" in the guru errors?

 

[LWares87]

Alleyway & Super Mario Land share the same addresses.

pc: 01000E48 addr: 00001FFF

Edit: if you need any other data, just ask.

Just spent an hour or so reading through this entire thread. The speed at which you're updating this piece of software is simply outstanding, keep up the good work! I haven't yet had the chance to test the emulator, but reading through the thread has made be a believer.

Drenn: About the nifi-issue where packets are being dropped by your DSi: Could this be a problem with your actual hardware? I think I read that it didn't happen as frequently with your DS/L, maybe your DSi's wifi chipperonis are failing? I only have one DS myself so can't really test it.

GBC IR over nifi would be swell though, Pokemon Crystal Mystery Gifts, anyone?

 

[Drenn]

I have mid-frame palette changes sort-of-working now. The Harry Potter games and Cannon Fodder look much better, though not perfect. Donkey Kong Country's titlescreen and Rayman (in-game) both look fine now.

Okay, fail on my part. It should actually be working now.

There's clearly something different about my dsi, nifi-wise. I'll see if I can borrow another regular ds to test it. IR shouldn't be too difficult to do, in theory, since it's wireless communication. I didn't really feel like doing it since so few games use it, but I will try it at some point.

This looks interesting.

 

[jose_exe]

Great work! This is already on par with Lameboy!

On the roms i've been trying [Beatmania GB, GB2 and gotta mix versions] has sound glitches [sustained tones, high pitched squeeks]
Also there is graphics issues with X ekkusu
[The tunnel scene its in black when it's suppose to be white]
and another one with PopnMusic Animated Melody
[when you are playing a song the background is black but is supposed to be blue]

Don't know if been asked before, but are you planning to implement an ini file for save settings?

 

[LWares87]

I can now confirm that both games (Alleyway & Super Mario Land) are now actually working with R4DS & 'hopefully' for other flashcards, as well.

Thank you Drenn.

Edit: Settings are saved as 'gameyob.ini' at the root of the MicroSD Card.

If this file is either moved or deleted, the default settings will be used.
