Multi-Mode 2 (MM2) Hex Code and Installation Diagrams v2.x

Version 2.0 *****BETA ONLY ***** 15/9/99
Total change to Multimode Code ... this code will (hopefully) run all games without
the need for "Dino Mode" .. it uses a completely different method to detect when to
send the code .. it is still under development and needs much testing.
This code is not compatible with PU7 board (Jap SCPH-1000 ) except in 4 wire mode.

Version 2.01
17/9/99
New in Version 2.01
Added Chip disable (Hold reset for 3 seconds)
Added Selectable 4 wire mode ( Hold reset for another 3 seconds)

Added User Selectable "Dino Modes" (Hold reset for another 3 seconds then each time you press reset
for 1 second then you change "dino Mode" ... 255 modes available BUT only the first 10 or 20 will
work ... this depends on your console ....

Version 2.01 was originally clased as a beta but has proved reliable.

Version 2.02 ****BETA ONLY****** 29/11/99
New in version 2.02 ... A few people have reported problems with some
batches of the 12c50xA chips .. this is because these batches have
slow running oscillators (3.8-3.9Mhz rather than 4Mhz) to fix this we
have increased the speed of the code in 2.02 beta ... it has had very
limited testing and should really only be used if you have problems
with the bad A version chips .... we currently have no information on
which batches are affected but they seem to be early 99 chips ..
