Re: New Game: Minesweeper

Thanks again for your help. I didn't consider the CPU being at 4Mhz would change the vdu timings. I'd optimized the code for the 3.5Mhz MSX CPU.

I've added a few more wait states around the vdu decompression and copy routines.

Re: New Game: Minesweeper

Thanks for the feedback.

I didn't realise CPM was in the higher memory. I've changed it to limit the memory to 21K.

I only actually use 16K, I just padded it make my life easier.

I've also added some wait states around the VDP decompressor.

(It did run fine in MEMU)
