As many of you know, I'm working on an improved version of the MSX-Audio BIOS.

But today the M80 compiler began giving me "Out of memory" errors...

Is there a good replacement for M80, either cross compiler or native MSX? It must be fully compatible with it, including macros and IFDEFs, as there's a lot of those on the code.

For cross-compilers, I would also like to know options either for windows, linux or mac-os X.

Also, tips to work-around the problem on M80 will be welcome. I don't know if it's possible so split the program in smaller files and have M80/L80 to build it automatically in a single ROM file afterwards.

Best regards,

Correction: It's L80 which is giving me "Out of memory" errors:

MSX.L-80 1.00 01-Apr-85 (c) 1981,1985 Microsoft
?Out of memory

I don't know if they're compatible with M80, but there are quite some cross assemblers available that work on all three platforms (pasmo, sjasm, z80asm, etc.). tniasm only works on Windows AFAIK.

Well if M80 is giving you out of memory errors, it's because you exceeded 48k on code... is that the case? Your "Bios" have more than 48k?!

Also, M80/L80 runs on MS-DOS prompt - Adriano had adapted it with both a .BAT file to compile your programs (CL80.bat) and 22nce.com (a utility to allow CP/M programs to run on MS-DOS) - just noticed there's also on Adriano's page a version that runs on Linux

to split files on M80 just put the routines you want in other files and include them into your main program:

include <file>

you can also include data like this... just convert any file to a bunch of DB (byte) and do something like:

MyRawData: include myrawfile.inc

(the .inc extension is just what I like to use, you can use any filename/extension you want, even other .mac's)

I found the problem. There was a DEFS $-addr,0 being crossed. This caused the M80 to generate a huge file of 130KB that L80 could not handle.

Anyway, thanks everyone for the tips.
