- When my CoSysOp uploaded this game to SECOM, he did it asking me if I
- could check it before validating the upload. Reason being he couldn't
- get it to work on his Falcon.
-
- Neither could I.
-
- I asked the people in comp.sys.atari.st if anyone knew what was wrong,
- and got this reply:

- I've found the bug (thanks to ADEBUG :-).
-
- At the address $4AB0 of the TEXT segment, you have to write $4E71 (just
- after 00 1B), which corresponds to a NOP instruction, to cancel the check.
-
- Explanations:
- At the address $4AAC, one has "CMPI.W #$1B,D7", where D7 contains the
- graphic mode. And at the address $4AB0, one has a BNE... i.e. if the
- graphic mode isn't $1B, the game doesn't start. But I think that with
- many monitors, the graphic mode is $3B (PAL flag = 1); so it doesn't
- work.

- I did the above patch, and it's the patched version you will find in
- this archive.

- Happy playing! (And remember to boot it in 640*480*256!)
