The conversions use a modified version of the M84-based game code created by Chris Hardy using his R-Type emulator.
Please note that these ROM image sets are not suitable for use with any emulator.
In addition to the 4 x 27C010 and 1 x 27512 already on Major Title that can be re-used, you will need the following items:-
|other games||none exist?|
The following ROMS need to be removed and 32-pin sockets need to be fitted in their place where applicable.
Blank all the EPROMS and program in the hacked images according to the list below:-
*_V0 into 27C010 for location IC12
*_SP into 27C512 for location IC15
*_C1 into 27C020 for location IC48 (C1)
*_C0 into 27C020 for location IC49 (C0)
*_H1 into 27C010 for location IC51
*_H0 into 27C010 for location IC52
*_C3 into 27C020 for location IC56 (C3)
*_C2 into 27C020 for location IC57 (C2)
*_L1 into 27C010 for location IC59
*_L0 into 27C010 for location IC60
*_N3 into 27C010 for location IC36 (N3)
*_N0 into 27C010 for location IC44 (N0)
*_N1 into 27C010 for location IC45 (N1)
*_N2 into 27C010 for location IC46 (N2)
There are few jumpers that need to be changed to reflect the EPROM memory configuration.
J2 (opposite IC12 pin 31) from "MASK" [--O] to " EP " [O--]
J4 (opposite IC48 pin 30) from " OT " [O--] to " 2M " [--O]
J5 (opposite IC48 pin 25) from "1MM " [O--] to " OT " [--O]
Locate IC7 (43256-12). Cut the track leading from pad 1 on the solder side of the board.
Use the wire-wrap wire to make the following connections:-
|IC7 pin 1||->||C36 GND||(len. 6mm exc. bare ends)|
