GG/PAR equivalent speed

Post by KanedaFr » Tue Mar 22, 2011 11:54 pm

I (re) read the gamegenie and PAR documentation but I'm stuck on one point : speed

Let say I want to make something like the GameGenie....
I check address asked and
- enable original cart only if I don't want to path the data
or
- return my own data

I think this process must be very fast...I don't know the speed of the SGA001 but it must be faster...

Do you think it's possible to connect to an external device (who said a PC ? ;)) and wait for instruction ?
If I'm not wrong, all must be done within a M68k cycle...so I doubt it possible...
I'm looking for a way to make on run-time patch...
