Irem M72 multi kit installation & support

Post by Arcade-Projects »

Important information:
Games aren't preloaded in the multi, users must download romsets by themselves then generate appropriate rom files with the tool (for Windows) provided here in attachment:

arcade-projects.com/forums/ind…9f3f042b5e95a3f1ba7c4d8a3

[color=#FF0000][/color]Steps:

1) Unzip all romsets at the same place


2) Unzip the M72_V2_ROM_GEN file attached, it contains:
- bps files for ROMs 01, 02 and 06
- M72_V2_ROM_GEN command file
- interleave.exe
- flips.exe


3) Simply run the M72_V2_ROM_GEN command file. It will generate ready to burn files for ROMs 01 to 10 (it's normal 03 doesn't exist):


Before burning any chip please check all files are exactly 4096kb in size except for 06 where it should be 2048kb.

Installation of the kit is solderless.
Kit is composed of two boards, one fit on the bottom board (background tiles) and the other one on the top board (main CPU code, sprites, samples), one 4 pin jumper cable, one universal GAL chip, one universal MCU chip and 6 PCB spacers.

1) Separate top board and bottom board from the middle board. On my boardset I had to separate the bottom board first by unclipping the two flat cables on one side , the small 4 pin power connector on the other side (JAMMA side) and then unclipping the spacer. Then I could access the 4 screws holding the top board.

2) Remove all ROMs/mask ROMs from the bottom boards (8 of them) and move jumpers as follow:
J2 = B
J3 = B
J4 = B
J5 = B

3) Install the smaller board from the kit, be careful no pin is bent or broken and check the position and alignment from the pictures below. The yellow arrow shows how the pins must be aligned with the socket underneath:

4) Connect the jumper cable to the square pins on the left.

5) Remove all ROMs/mask ROMs from the top board, so as the PAL chip and the MCU chip and move jumpers as follow:
J1 = A
J2 = A
J3 = A
J4 = A
J5 = B
J6 = B
J7 = A
J8 = empty
J9 = A
J10 = A
J11 = B
J12 = A

6) Install the bigger (really big!) board, be careful no pin is bent or broken and check the position and alignment from the pictures below. The yellow arrow shows how the pins must be aligned with the socket underneath:

7) Install the universal GAL chip and MCU chip (in the yellow rectangles on the picture above). Check notches match the silkscreen/original positioning.

8 ) Replace the spacers between the middle and the bottom board. 6 longer spacers are provided in the kit as few more millimetres clearance is needed once the kit in place:

9) Reassemble the stack and connect the jumpers cable to the square pins of the top board of the kit. Wires must be flat (bottom pin connected to bottom pin on the other board, etc.)
