Assembly: Paula sound?

Posted on: 2013/1/10 1:14 #1

I have no clue what I'm doing wrong.
I'm trying to get some sound out of EUAE, I'm using the Amiga Hardware Reference Manual,
page 146, if I'm not mistaken audio has to be in chip memory? So it can't be part of program code?

So I have changed the example a tiny bit.

Ok, I did some thing stupid here, trying to play sound before I setup the sound wave.
I will try to fix this when I get home.

You're using Paula a custom hardware with its hardware registers, so yes it uses the chip memory.

I've tried in the past to write 68k code under WinUAE or EUAE, but it's not the best. Better to write machine language programming in real classic hardware.

Don't have any hardware whit this chips anymore, anyway I find it interesting that CUSTUM or HARDBASE is constant that is often loaded in register, so it should relatively easy to move hardware from a fixed address to a PCI card, if you have the source code.

I was thinking if I replaced

MOVE.W #8201,DMACON(a0)

Whit something like this

MOVE DO,-(SP)
MOVE #8201,D0
JSR .SET_DMACON
MOVE.L (SP)+,D0

It might be simple to emulate DMACON on AHI, whit in an application.

EUAE does not make a peep, but I fixed a few mistakes, I hope some one can tell me what the problem is.

@flow
Nellepuh does not work whit AmigaOS4.1 only 4.0, it conflicts whit something AmigaOS4.1 does, maybe CUSTUM address is not reserved address space.

Anyway old software have number of problems, wrong timing, don't use timer.device but instead uses CIAA and CIAB timers, read joystick IO from fixed hardware addresses and so on, so if you really like something to work, you need to disassemble it, fix it and recompile it, then you create a binary patch.

On Aminet there is a package for disassemble Amiga executable hunk files.

http://aminet.net/package/dev/asm/ira

you can then use 680x0 compiler like the one provided whit vbcc

http://lifeofliveforit.blogspot.no/20 ... opment-enviroment-on.html

Nellepuh is not doing the same thing, Nellepuh is catching illegal read and write operations using the MMU, and then handles emulation whit interrupt routine. Nellepuh does not correct timing or make program more system friendly.
