I started on arcades working on CAPCOM systems from the 80's. All these cores work well, but they have some technical debts that I'm paying back

Digital voice recording is the simplest yet trickiest sound synthesis method. Simple as it is kind of obvious what you're doing; tricky as it can eat up all the memory you're willing to give. Digital recording made epic moments in arcade games, let's go for a tech overview

We continue working on the SEGA System 18 schematics from PCB. This board is especially difficult due to the large number of custom chips with ~100 pins each. I think it will take the whole month working full time to complete it.

CAPCOM understood it and went as far as to have one of the CPS background layers use 32x32 tiles, with 16 colours. So CPS offers three different layers, each with 16 colours per tile and different tile sizes: 8x8, 16x16 and 32x32
