Ghostlop MVS conv.

[Vendest]

Hi,

I Hope someone can shed some lights regarding the jumper settings for board PROG-G2 & CHA42G-3.
The game goes in bootloop mode after the DATA EAST screen and sometimes will clear till "How to play" followed by an address error.
Not sure if it is due to a bad rom or jumper settings.
I think P1 is now set to ROMOE and C rom don't require chunk swap.

Thanks

Use a different PROG board that will acommodate an LS108

Thanks! In the end can the PROG-G2 be used for other conversion?

Did you swap pins for S1?

Did you swap pins for S1?

Pin 2 and 24? No I didn't

Pin 2 and 24? No I didn't

Is it bit swap? What type of EPROM is it? It doesn't look like an Eeprom, but a one time used chip. Thx

It's a mask rom MX27C1000.
Now that you mention about it I didn't have to swap pin 2 and pin 24 on the programmer unlike the Eprom I tend to use.

I would just check the pin out matches to verify that isn't causing anything weird with addressing.
