Re: Atari ST Diagnostic Disk (Heavily Protected)

It's 68000 assembly language, or "assembler". It's not compiled it's assembled, by an assembler such as GenST.

Seemingly the file was assembled with the symbols hence it looks quite readable due to all the labels.

Re: YM + digidrum won't work

Could it be something to do with your playback code rather than the data in the music files? When I ripped the Chambers of Shaolin music (the first with digi drums on the ST) the soundchip part worked fine but there were no digi drums. Turned out that the MFP interrupt at $114.w also had to be setup...

Re: Trying to find the name of an adventure game

A USB floppy drive should be OK, I've transferred stuff with one of those OK under Windows Vista and 7. At least it works with the HP branded USB floppy I got years ago (manufactured 2006 it says on it). You can use a DD (Double Density) floppy or a normal PC HD (High Density) floppy with a sticker ...

Re: How to detect all available memory (used and free)

For the total RAM size (as detected by the BIOS on boot) you can check the system variable "phystop" at address $42e.w , from super mode. eg. it'll be $80000 for a 512K machine or $100000 for a 1MB machine. Or if you want user memory rather than total memory you could calculate it from the...

If it's a normal Rob Northen Copylock protected disk and you want to make a working protected copy from a non-working image you could try using the attached util to copy it over any other working copylock keydisk. It just copies the part required for calculating the "magic number" and leav...

Re: "WTF?" issue - help

Yes, the "a" just means that the destination is an address, when I was doing a register move I'd just type it as "move" in the source code and let the assembler sort it out, only when you disassembled it would it appear as a move or movea as appropriate. I think "lea" i...

Re: "WTF?" issue - help

I'd love to know what (and why the movea instructions cause that bug - still not sure, having read more on it). It's not a bug, the movea and lea instructions are meant to do different things, the only strange thing is that the assembler is changing the lea to a movea. Unlike other instructions, le...

Re: "WTF?" issue - help

Yes, the only problem is that the assembler is changing the LEA to a MOVEA for some reason, thus making the code do something entirely different and unintended.

Re: "WTF?" issue - help

It's been a long time since I did this stuff but I'm pretty sure that "lea $c(a1),a2" is not the same as "movea.l $c(a1),a2" The first one will result in a2 = (a1+$c) The second one will result in a2 = the longword stored at address (a1+$c) No idea why GenST would be assembling a...
