NitroGrafx - PC-Engine & TurboGrafx-16 emulator

[FluBBa]

I seem to have the same rip of Baby Joe and it works fine for me. Are you testing on HW or on an emulator? I think most emulators don't support more than 2GB at a time for folders/cards, which is just 2-4 CD games at a time.
Also NitroGrafx only supports single-file rips, I might look into that before a real release, this test was mainly for ADPCM.
Edit: Here is a new test version with a fix for a crash in ADPCM DMA.
Edit2: see next post.

testing on real DSI hardware, Baby Joe is now working with NitroGrafxTest2,
i just tried Lords of thunder that was working with 1st test build and it gave me the same load error,
but maybe this was random error because after activating the "on/off" option, and reload again, it works normally.

Tengai Makyou is now able to pass the intro but with some sprite glitches and audio scratch before ADPCM

edit : for baby jo, i could finish it (it is terrible but good to test samples playback) : sometimes ADPCM don't play . for example, i don't hear the bottle-feeding sounds when he suckels.

Bubblegum crash (hucard game), rightmost tile disapearing during facial animation (in both japanese and translated rom)

coudn't test more, my rips are 'multiple bin'

I'm tweaking how to calculate the length of the samples right now. might have a new test file soon.

Here is a 3:rd test with better ADPCM length handling.

baby jo - samples playblack seems now correct

Tengai Makyou - now gfx glitches are no more but later in intro, speeches are truncated or don't play

volfied - a strange "pointer" error , when you finish a level, the bonus countdown is infinite
and the background sine-wave sound stays locked on a single note

Jigoku meguri - in level two, the eerie music that is normally whistled is distorded and off key (i suppose it's already known but maybe linked to ADPCM)
i leave my savestate here.

Dragon egg - Black screen
Energy english patched - grey screen after entering name

ADPCM is only available on the CDROM so it should not affect normal HuCards. Dragon Egg is documented in the readme. Energy works for me, does it work in other emulators for you? Volfied I need to look at/document. The length control for ADPCM should be quite accurate now, will post new version soon.

This is really cool! Man, I wish the DS was easier to emulate. I might have to dig out my old rom loader, nothing really replicates a touch screen quite the same.

Here is a new version where adpcm streaming seems better.

Thanks for your incredible work, FluBBa, and also to Garcimak for answering my questions; I think I'm ready to report my observations on games that have issues with version 0.9. The first one is
*Soldier Blade* (USA version), MD5: 441fea810ecb8e453d96ae9501e12e9c.
The game always freezes after completing the first act, as shown in the screenshot; the issue also occurs when using NitroGrafxTest3 and NitroGrafxTest4.
Issues were also found with the game *Ginga Fukei Densetsu Sapphire* that did not exist in version 0.9; these are minor graphical glitches, as seen in the second image.

i had trouble getting anywhere in the menus than a black screen with the last build.
that was the previous settings, thanks for the continuous support.

my bad , i was confusing PSG and ADPCM

now multiple bin can work testing rainbow island, psg partily works (except some like collecting sfx)
but ADCPM doesnt. horizontal screensize is a bit to thin though (256px?)

buster bros ( multiple bin cdrom) - harsh garbage sound , very low psg

Monster lair (single bin) - game seems more alive than ever with psg playing and balanced mix

lords of thunder (single bin) - great audio seems all effects are playing although the mixing enveloppe a little on the low side with dsi audio at max.
