 This install applies to "Gem'X" © 1991 Kaiko.

 Requirements:
 -------------
 This install requires WHDLoad and RawDIC to be in the path.
 These programs can be found in the WHDLoad package.
 To install from a different drive than DF0: select installation mode Expert.

 The installed game requires 0.5 MB ChipMem (+1.0 MB OtherMem for preload).

 It can be quit by pressing F10 (key can be changed with Tooltype "QuitKey=").


 Features:
 ---------
 - Full load from HD
 - Protection removed (MFM, longtracks)
 - Interrupts fixed
 - DMA wait in replayer fixed
 - Copperlist termination fixed
 - Timing fixed
 - Bugs in TFMX replayer fixed (thanks Don Adan)
 - High-score load/save
 - High-scores can be set to default values with CUSTOM3
 - Trainer options added (high-score saving will be disabled if used)
 - Keyboard routines rewritten
 - NewIcon (created by me)
 - Source code included
 - Quit option that works on 68000 machines (default key is 'F10')

 And here it is, the all new and shiny patch for Gem'X. Yesterday
 I fixed problems with old patch and once done I decided to redo
 the patch completely and this is the result of a few hours of
 work. Done while listening to tracks by Katja von Kassel (highly
 recommended!), Diorama and Diary of Dreams. Good music is essential
 for coding. :)

 First I coded a RawDIC imager and then patched the intro and the
 game. Not too hard to do as the code is fine! I've also fixed bugs
 in the TFMX replayer that were found by Don Adan (thanks!).
 This new patch also supports high-score load/save.

 Please note that you have to re-install the game!


 Notes v1.4:
 -----------

 Since the high-scores are saved to the game binary in the disk version
 I had to adapt the version check to work with binaries with modified
 high-scores. I have also added an option to reset the high-scores
 to default values, if used the "GemX.high" will contain the high-scores
 of the unmodified disk version.

 Additionally I have also added a few trainer options (which, in my opinion,
 spoil the game), if any of these options are used the high-score saving
 will be disabled.


 Notes v1.5:
 -----------

 Harry reported that the random number generator used in the game used
 the raster beam position so it didn't produce good results on fast machines.
 I have recoded the random generator not to rely on the raster beam anymore
 which gives much better results. I have also fixed the in-game timing
 as the game ran too fast on fast machines. Thanks to Harry for reporting
 the problem with the random number generation and a really excellent
 bug report, if all reports would be like Harry's the life of a patch coder
 would be much easier! :)


 Enjoy this classic from HD.
