Virgil Dupras	97a46a7b9b	emul/z80: decouple SDC and SPI ... My idea of plugging a RC2014 bridge directly onto a Sega Master System cartridge doesn't work. The SMS eats all I/O addr space, we can't use it. Therefore, this naive idea, in the emulator, of reusing sdc.c in sms.c as-is, doesn't work either. I'll have to find another way of communicating to a SPI device on the SMS. I'll probably do it through a controller port. Meanwhile, I need to decouple SPI from SDC in the emulator code so that I can reuse sdc.c. This is what is done here.	2020-10-29 15:01:25 -04:00
Virgil Dupras	705d68deec	Move most of the high layer of comp core into the low one ... With KEY and EMIT being switch words, most of the high layer can be defined before drivers. In addition to this change, I've compacted core blocks which were becoming quite sparse.	2020-10-28 18:18:00 -04:00
Virgil Dupras	91f79d1131	Move z80a from B200 to B5 ... The idea is to consider assemblers as "runtime" apps instead of placing them in the "bootstrap" section of the blocks. These apps will be used for much more than bootstrapping. Moved its documentation to doc/asm.txt and made its code blocks more compact.	2020-09-21 17:51:08 -04:00
