By default, allocate about 0x100 bytes for PSP+RSP During "make updatebootstrap", we use less than 0x20 bytes on the PSP side and less than 0x40 bytes on the RSP one. 0x100 bytes ought to be enough for anybody. 2020-05-15 08:41:09 +10:00			`0xff00 CONSTANT RS_ADDR`
Replace INITIAL_SP with PS_ADDR conf Now I struggle to remember why I ever did things they way I did. There must have been a reason... 2020-05-12 11:08:24 +10:00			`0xfffa CONSTANT PS_ADDR`
Rename RAMSTART to SYSVARS It's more descriptive this way. Also, I'll soon add a new HERESTART config. 2020-06-29 08:49:30 +10:00			`RS_ADDR 0x80 - CONSTANT SYSVARS`

z80: make boot binary a 2-part process Previously, recipes that began spitting binary contents before loading block 282 would end up with VARIABLE code in their binary, thus breaking them. We fix this by making this loading process 2-part. 2020-06-27 11:41:17 +10:00			`212 LOAD ( z80 assembler )`

Streamline initialization process Instead of letting each configuration taking care of RDLN$ and "CollapseOS" prompt, move this to BOOT to simplify xcomp units. Initialization source code is now only for driver initialization. 2020-05-16 01:34:35 +10:00			`," ' CR 0x0a RAM+ ! BLK$ FD$ " EOT,`
xcomp: move all offset spitting to the end of the unit I'd like to move this code, along with all recipe contents, to blk/. It's easier if "emul-related" code is gathered at the same place. 2020-05-06 10:10:04 +10:00			`ORG @ 256 /MOD 2 PC! 2 PC!`
