Chuck Rock ozisoft
Post Posted: Sat Jun 27, 2020 12:50 pm
Can’t find any information on this ozi soft release of chuck rock ive got. Didn’t mean to purchase another copy on eBay , ended up having a double up. But keeping both now. All I can find about their releases is they have a silver box and this game isn’t listed.

One made in Australia by ozisoft and another made in Japan. One has a resistor where the other has a tantalum capacitor.

Both have electrolytic capacitors at the bottom but soldered in different holes.

One has a couple extra active traces to pins that connect in the cart slot

Ozisoft one is Phillips head and normal looking label and the Japan Sticker one is gamebit screws and white label.

Would these be different ROM versions ?

The MPR number identifies the ROM data. Can you confirm what it says?

Looks like SEGA / MPR-14581 W16 / 9247EY001

edit: sorry, had a one-digit typo before!

edit 2: i see what you mean, it might be 14581 or 14531 and the photo isn't clear enough to really tell

Ozisoft never had the resources to create their own versions of the ROMs, did they?
