I had a spare one of these that wouldn't work, so I opened it up and it was missing the BIOS chip :banghead:Anyway, I took some photos of the insides. It seems to be a very well made (in Japan) unit with a Teac floppy drive, and Panasonic backup battery. Mainboard with 32M Memory 32M Memory bank Cartridge connector & AdHoc board markings (with date) Panasonic Lithium Coin VL2330 3V backup battery (rechargable) CPU, Decoder chip SNC4011 and memory socket Parallel port & reset switch Unit without casing 1 Unit without casing 2 Cartridge connector to mainboard connector 1 Cartridge connector to mainboard connector 2 Cartridge connector to mainboard connector 3 Cartridge connector to mainboard connector 4 Teac FS-235HF Floppy Disc Drive Jumper pins (NTSC) 1 Jumper pins (NTSC) 2 For the jumper pins, it would be interesting to know what the settings are for PAL use. If anyone has a PAL unit that they can inspect, please let us know the differences. I am assuming that the U10 SNC4011 Decoder chip would need to be replaced with a PAL CIC?.
I think as is the same on most Wildcards most of the jumper pins are there to select between on-board CIC or the CIC on the inserted game cart. To change to PAL it might be that you can just drop in a PAL CIC.
Yes I've been doing a bit more research, and it does look as though once the CIC is changed, moving the jumpers to the left by one space will make it PAL compatible. It seems that from the current jumper arrangement of: 0 1 0 1 0 1 1 0 1 0 the following are critical to NTSC operation: 0 1 0 1 0 1 0 0 0 0 a suggestion for PAL operation would be: 1 0 1 0 1 0 ? 0 ? 0 ....with some option for clearing BIOS SRAM with 13-14 and 17-18 (trial and error). 0= no vertical jumper 1= vertical jumper ?= not sure I'm going to remove the PAL CIC from a copy of FIFA Soccer (I think it has a D413A CIC), and run some tests on a working unit I have.
