$subj. Or maybe even older versions?

The old Java-based decompiler by Clam fails on some GM 7.0 executables, for example:

I can provide all the formats info if necessary.

Anyway thanks.

My main concern with GameMaker 7 is that there's a version of anti-decompiler protection for it (antidec1), so I would have to spend time reversing that in order to fully support GM7. Aside from that I don't suppose it would be too much trouble. Do you know how different the GM7 exe format is from GM8.0? Does it use any different encryption methods? Also, what is GameMaker 7's GMK format and how similar is it to GameMaker 8.0 - would it be easily compatible?

AFAIK it's not different at all.
