crem Posted April 28, 2021 Author Report Share Posted April 28, 2021 Thanks, it was indeed a bug on my side. When I saved/restored states in Manic Miner, I saved some memory locations and all registers. For JSW, I thought that there's no need to store registers as when frame starts (pc=#89ad), none of registers are expected to have meaningful value. But actually the PC itself may be wrong. If during the previous attempt Willy hit a guardian (and breakpoint at #8c01), it's not enough to just restore the memory, PC has to be restored too. I'm not sure whether any other register matters at that point (SP maybe?), but just to be on the safe side, I'll include all registers into the state. jetsetdanny and IRF 2 Quote Link to comment Share on other sites More sharing options...
