Update to v101r27 release. byuu says: Changelog: - SMS: emulated the generic Sega memory mapper (none of the more limited forms of it yet) - (missing ROM shift, ROM write enable emulation -- no commercial games use either, though) - SMS: bus I/O returns 0xff instead of 0x00 so games don't think every key is being pressed at once - (this is a hack until I implement proper controller pad reading) - SMS: very limited protection against reading/writing past the end of ROM/RAM (todo: should mirror) - SMS: VDP background HSCROLL subtracts, rather than adds, to the offset (unlike VSCROLL) - SMS: VDP VSCROLL is 9-bit, modulates voffset+vscroll to 224 in 192-line mode (32x28 tilemap) - SMS: VDP tiledata for backgrounds and sprites use `7-(x&7)` rather than `(x&7)` - SMS: fix output color to be 6-bit rather than 5-bit - SMS: left clip uses register `#7`, not palette color `#7` - (todo: do we want `color[reg7]` or `color[16 + reg7]`?) - SMS: refined handling of 0xcb, 0xed prefixes in the Z80 core and its disassembler - SMS: emulated (0xfd, 0xdd) 0xcb opcodes 0x00-0x0f (still missing 0x10-0xff) - SMS: fixed 0xcb 0b-----110 opcodes to use direct HL and never allow (IX,IY)+d - SMS: fixed major logic bug in (IX,IY)+d displacement - (was using `read(x)` instead of `operand()` for the displacement byte fetch before) - icarus: fake there always being 32KiB of RAM in all SMS cartridges for the time being - (not sure how to detect this stuff yet; although I've read it's not even really possible `>_>`) TODO: remove processor/z80/dissassembler.cpp code block at line 396 (as it's unnecessary.) Lots of commercial games are starting to show trashed graphical output now.
