PC-88
Here's the PC-88 version of it, home to the adult japanese games !
A PC-9821 version may come at a later date but this one was the easiest to do so that's what i did.
The PC-88 has one of the biggest VRAM amount considering its 8-bits CPU : 48kb !
Despite this, it still manages to be faster than some of the older computers although it clearly struggles and you'll also be fighting against RAM. (as 16kb gets temporarely cut)
Thankfully the PC-88, unlike some Russian computers or the TIKI-100, actually maps said VRAM in chunks of 16kb at the end of the memory. Not as clever as Commodore did but still good. It's just that this platform tries to chew more than it can do.
I had to cheat a little bit in game by only updating 2 planes instead of 3. This gets me 4 colors instead of the usual 8 but that's fine because it looks similar enough in our case and it also saves memory. Despite that, it's still not fast enough so you can still see some of the "greenish" updates but i thought it looked acceptable enough despite that.
There is a version for tape/cassette as well as floppies (D88). The floppy version is self booting so all you need to do is insert the floppy in slot 1 and reset. Make sure you have N88 otherwise you'll only get B&W graphic.
The cassette version is not self booting and requires a few commands
MON
R
Select the tape file (Or play your tape on real hardware)
