Tiger Heli (US)

0.34b4 [Nicola Salmoria]


NOTE:

- The MCU protection in Tiger Heli is very simple. It compares for a value to return a specific number, otherwise it will give the BAD HW message(stored at locations $10AB-$10B5). The program itself says what kind of value is needed (usually,but not always 0x83).This is simulated by reading what value the main program asks,then adjusting it to the value really needed (as it was managed by a real MCU). The bootlegs patches this with different ways: The first one patches the final 'ret z' opcode check with a 'ret' at 10AAh. The second one patches the e803 checks with a 'ret' at location 109Dh.


DIP/Input Bugs:

- Clone tigerhb1: When the "Bonus Life" Dip Switch is set to "20000 80000" (which is what you can read in the "test mode"), you in fact CAN'T get ANY extra life (even when collecting 10 "diamonds"!) due to code at 0x1082 (see text file). tigerhb1061gra stephh
