- The patch necessary is only a few bytes long, so I don't upload it
- to any ftp site. Instead I give you instructions how to do the patch
- yourself.
-
- General Instructions:
- - Use a diskmonitor
- - read block 1066 (that is track 48, head 0, block 10) of the
- Maximum Velocity disk
- (the first words in this block are 33fc 7fff 00df f09a)
- - change the bytes starting at offset $78 (hex) (i.e. 120 decimal)
- to the following: 46fc 2700 4a39 00bf ed01 13fc 0000 00bf
- ea01 4e71 4e71
- (the bytes before offset $78 are 8008 00df f09a 4e75; these
- must remain the same)
- (the bytes after the ones you change are 13fc 0000 00bf e801)
- - write back the block (don't compute a checksum)
-
- Special instructions if you are using C-monitor:
- - start the c-mon and put the MAXIMUM VELOCITY disk in df0:
- - enter: <s 50000 48 0 10
- - enter: e 50078
- - enter: 46fc 2700 4a39 00bf ed01 13fc 0000 00bf ea01 4e71 4e71
- - press return again
- - enter >s 50000 48 0 10
-
- After this patch the demo should work properly. If you have any problems,
- feel free to mail me. If the patch works on your amiga, i'd be happy to
- hear about that, too.
