Re: XA Format Specs

Got it folks! It was the Filter.........bad parenthesis! Error: sbyte filter = (sbyte)(parameters[4+block*2+nibble] & 0x30 >> 4); Correction: sbyte filter = (sbyte)((parameters[4+block*2+nibble] & 0x30) >> 4); Simple order of operations whoops! Thank you for your support, Shadow and NoCash!

Re: XA Format Specs

So I can see the pattern is there, at least I have the blocks/samples in the right order for both channel. Just doing some shifting or something wrong as it seems I'm getting much higher (or lower) values than I'm suppose to which make the wave forms look very large. Here is a comparison to the same...

Re: XA Format Specs

Yeah, I wish I could just breakpoint PSX and follow the assembly to figure it out :P Short is a signed 16 bit, so yeah it already has the min/max, whoops! To test it, I even break pointed the return min or max lines and they are never hit (even after changing the type to be shifted to int32). Ah yea...

Re: XA Format Specs

Hi. Guess I celebrated too early on the XA audio. Are you willing to double check my work? I understand if you're too busy or do not want to so don't hesitate to say no. I know I'm close. I hear a voice but it's mixed with some static. I can tell the wav has some +32.768 or - 32,768 areas that shoul...

Re: XA Format Specs

Thank you so much! With your help I was able to read and play XA audio. I'll use your document since it explains it better :)

Re: XA Format Specs

Has anyone had success using this documentation? I'm writing an app to convert XA files just for kicks (I know there are some out there but they don't work on win7) and everything seems to be legit until it comes to converting ADPCM to PCM. It looks like the documentation is wrong, since the pseudoc...

Greetings, about time I found this community!

I thought I was alone and vastly out-dated in my recent (but powerful) interest in psx debugging. I am so glad I found this site with people that know what they're doing. <Boring spiel about me> Not to say I've been unsuccessful, but everything I know was self taught or from very outdated random for...

Re: How do I figure out which file an instruction is loaded

I think you misunderstand what the gameshark is doing, or I'm really confused. It's not changing the file or instruction set, it's changing the memory. You took the memory address from the gameshark code and it looks like you went to the PC address of the assembly instead of the memory? Did I get th...
