For curt

[sermajic]

Hi there

 

Noticed games like h.e.r.o. Work on flashback 2 from harmony cart

Though they dont from the real cart

 

Batari needs help from curt to get pitfall2, fatal run etc run on flashback2 with

Modified roms from harmony

 

Heeeeeeeelp curt!

The problem is that the A12 line is always high on the FB2 so there's pretty much no way to tell the difference between a TIA access and either an access to Pitfall II's DPC registers or Fatal Run's (and others') SARA RAM writes.

 

Perhaps someday the FB2 designers will tell us if there are any signals available to us on the "Michelle" chip that could substitute for the A12 line and make these games work.

Essentially, what may help here is if Curt could tell us if there is a chip select or output enable line for the FB2's ROM, a signal that tells us if the Michelle is accessing TIA or RIOT areas, or anything else that might work. This would make nearly all of the non-working games work.
