Homebrew Game Rhythm8: Black screen + Audio on launch, no rendering modes fix it

[Alo81]

The software I'm testing and that is most important for me is the homebrew software Rhythm 8.

It loads up fine and you can hear the music as it starts but it sits on a black screen. I've tried all the rendering modes but nothing fixed it. I tried disabling stencil and that didn't fix it either.

I'm using the 64bit version of PPSSPP.

I've also tested the 32bit version and it still didn't work.

If someone could help me with this I would be really, really grateful because this is the one program I spend the most time with my PSP on.

Moderator's edit: Here's a download link to the homebrew in question: http://wololo.net/downloads/index.php/download/508

This post has a debug log from 0.9.5-763-g345d362.

Can you be more specific? What versions of the emulator have you tried? Are you using stable builds? Git builds? Has it ever worked at all?

Can you post a debug log?

Can you be more specific? What versions of the emulator have you tried? Are you using stable builds? Git builds? Has it ever worked at all?

Latest stable version - V0.95, it has not ever worked though I have only tried on this version and a previous one in the 0.8~ range.

The reason I think it might simply be a setting that's able to be changed is because the game is definitely running because I hear the notable stab that it starts with and I hear it fade appropriately when I press a button like it normally does on a PSP.

It seems to display graphics with 0.8.1 official, and Display Raw Framebuffer being set to enabled, but it seems to hang once you get to a certain point. So I guess this has never worked correctly, sadly.

Edit: Here's a debug log from release mode, 0.9.5-763-g345d362, 32-bit, Windows:

Here's a debug log from the same version as above, in debug mode: http://www.mediafire.com/download/5homc0...ug-log.zip

Edited thread title to reflect that it's a homebrew game.

This homebrew seems kinda neat.

Using the GE debugger, it uses memory locations 0 and 00088000 as framebuffers.

I created an issue on Github for the black screen stuff. It's not local to just this one homebrew.

Try the software renderer, btw; it seems to work in 0.9.5. It's very slow, though.

[TheDax]

This homebrew should work fine (at least graphically) with default settings now in the latest development builds. Just make sure Simulate Block Transfers is turned on.

Just wanted to post that this is true, it's been working fantastically as of late and all functions work as intended. I've been spending a lot of time in it and making great stuff thanks to the developers!
