Me, I take the executable binary and I hack from the binary itself.

Most old Atari ST games are written the same way, an executable with all the game code, and usually loads up graphics from separate files.

I pick my conversions quite carefully after the debacle that was Super Sprint. That was a VERY system intensively written game, which means more system calls, and certainly more than I could comfortably interpret, as my experience with the ST wasn't very high at the time, its quite a bit better now! So I generally pick games that are coded more similarly to most Amiga games, i.e. they might use a little bit of system to load some files, but usually once thats done, the system is then not used and its all "hardware" banging from that moment on.

Certainly easier to spot the palette stuff, screen base address stuff, for me at least.

Some games are quite easy to work around, others are highly irritating, French games are usually quite irritating, Meynaf is welcome to as many of those as he wants lol
Incredible! I will certainly give this a go once I'm back home... I will write the ADF hopefully if the CF isn't playing up again! Either than or convert from ADF to SCP and write using Greaseweazle!

I can't imagine the difficulty in putting this together but from what you're saying, it's way beyond me... I am happy to enjoy the final results of your labours! Lol
