Re: Anyone to convert a Z80 music player?

RIght, so a couple of clerical errors fixed and now it seems to sound like it should :D.

I'll provide emulator recordings tomorrow so people can listen and compare but it does sound very close now!

Re: Anyone to convert a Z80 music player?

Hey, that's great, fantastic work :). dc.b 8 : dc.w Main_Subsong0_RegisterBlock_784 + 1 ; Optimization: goto common Block at index 1. No ST assembler I know of recognises this - can we please have two separate lines of dc.w? Really? What kind of crappy assemblers are you using :) ? Well, I can add ...

Re: Anyone to convert a Z80 music player?

Okay, I spent some more time on the player - it now actually plays something that resembles music :). I'll need to do a more careful listen of the original and compare it with what's played, or make a specific tune so I can compare differences easier. Anyway, progress! (github/bitbucket updated, any...

Re: Anyone to convert a Z80 music player?

A small update here: now the player can init and play a song, it even outputs things to the ym! However it's still doing something wrong and loops early (after playing about 2-3 notes?) but hey - progress! If targhan is still reading this, I have a couple of small requests for the exporter: a) In ce...

Re: Anyone to convert a Z80 music player?

So for anyone that cares: I just finished a 2nd pass at the source code, tidying up things and taking care of loose ends. Which in practice means: a) It's now ready for debugging (so far I've been writing code at blind, so tons of bugs expected!) b) It is most certainly not optimal! For now it's si...

Re: Anyone to convert a Z80 music player?

Yup, thanks for the replies. I was mostly concerned about song length and limits, how much you can cram into 64k. I'll forge ahead with a 64k aligned buffer (because that's the easiest - adding support for non aligned buffers is mostly trivial and will take a slight more amount of cpu time). I just ...

Re: Anyone to convert a Z80 music player?

So hi again, Today I finished porting over the player code at sort-of-blind mode. It definitely doesn't work right now but at least it assembles without errors - woohoo ;). Of course during this first pass I did get an overview of the file format, and then I opened the editor and played with the exp...

Re: Anyone to convert a Z80 music player?

Hello! Wow! That's great! HOWEVER: you should have asked me before starting, you should NOT convert the "stabilized" player, because it only means something on an Amstrad CPC (each instruction always takes the same cycles, so it's rather easy for us to have "stable" code. Too bad...

Just for the heck of it, I started converting the z80 code line by line, trying to accommodate for small changes but not seeing the big picture yet.

Re: Cacheable areas on Falcon?

Not really a good idea when using TOS. Not only that you would have to copy the whole memory area of vectors first (because that change applies to *all* interrupts), And where's the problem with that? It's not like you need to copy around megabytes of RAM. but there are also certain routines in TOS...

Re: Anyone to convert a Z80 music player?

Is the 6502 player source available? Then we could use something like mos2mot to bring it to 68000 and add platform specific stuff and optimisations with a couple of passes.

Re: Cacheable areas on Falcon?

If you specifically want to play with the interrupt vectors, a good idea might be to change the VBR and have different sets of interrupt tables ready.

Re: bexa64n

Hi! Surprise, a big borders game :lol: The Jaguar is probably the most powerful 2D console ever or in the top 3 in any case; much more powerful than a NeoGeo. The 2D is not really the specialty of Falcon even if it is not bad (cf Sho ren sha); he is more gifted in 3D than in 2D thanks to his DSP. To...

Interesting project! Would love to play the Jaguar version.

Re: A year later

It all looks correct apart from the "shared folder path" - in my experience just the folder name is needed. So instead of "//XPS/Atari" try "Atari".
