Chihiro Type 1 Communication Error

[Bods]

Just been testing Chihiro setup I got a few years back, I connected up in my Initial D cab and after a few errors, pic chip wrong way in holder and jumper settings changed from netbooting it's all working with outrun 2 disc and type 3 media board

Thought i'd try Crazy Taxi High Roller on the Type 1 Media Board but all I get is Communication Error, green status LED on Chihiro is ON and then it starts flashing after a bit and both Green & Red are on Solid on type 1 board, assuming Red on isn't good!

Is it pooped? can't find any reference to this issue

Not knowing much on these I tried everything and it's quite misleading just saying Communication Error as it can be a few things I find out, then had a thought, my Netdimm is 256mb and Chihiro use 512 so tested some ram and changed to 512mb and hey it works Crazy Taxi High Roller
