Forum Recovery: An old backup :(

Here is a heads up about a problem with this. If you visit the Main Page, or the Downloads page, and try to log in, you get redirected to a 404 error for any page on the site you try to visit, since the forced change password URL only exists in the forums, not on the main page. I had to clear my coo...

Fails Blargg's GB-Z80 CPU Test program

Blargg made a GB-Z80 testing program: http://h1.ripway.com/blargg/temp/gb_cpu_test.zip   Among the instructions that fail are: E8: ADD SP,nn F8: LD HL,SP+nn   Those instructions are quite deceptive with what they do to flags: They use the lower byte of SP added to the unsigned byte to determine ha...

A new, and correct sound test program this time...

First, I'm sorry about the crappy misleading sound test program I posted previously. Here's a real sound testing program.   The program repeatedly plays a middle C note every 64128 GBA clock cycles, with the reset flag turned on. It fades the volume down by setting a new volume every 30 writes. GBC...

Logging VBAPRINT directly to a file?

I'm using VBAprint to output HUGE amounts of text, like maybe 300MB. How would I go about logging it to a file instead of having it get slowly placed in a textbox?

Forums are too subdivided

Forums are far too subdivided for the number of posts they are getting right now. I think you should unite Bugs, and Support, and all their subforums into one forum.

Broken/Messy Audio core - Dwedit's GBC emulator for GBA

No. It just writes to a sound register (I think it's to turn on the speakers, not completely sure), then reads it back to make sure the speakers are on. It freezes if it doesn't read back 0x80.


Works on hardware, fails in the current timing nightmare of VBA's sound code.

Broken/Messy Audio core - Dwedit's GBC emulator for GBA

I know that the Zelda oracles games write 0x80 to one of the GBC sound registers (forgot which one), then immediately reads it back to see if its value is 0x80. If it's not, it crashes.

Broken/Messy Audio core - Dwedit's GBC emulator for GBA

I think I'll take a look at this. How do I grab the SVN version and compile it?

 


edit: Hmmm... I don't have VC2008 (I'm still a VC6 user)

 


Okay, how exactly is the sound timing code supposed to work?
