Cleaned up Virtal Boy slot code.
vboy.xml updates: * Set width and endianness for all ROM regions * Added width and endianness for SRAM, assuming all cartridges have 8k*32 SRAM for now * Removed mirroring - this is an implementation detail * Removed "slot" features - there's enough information to work this out anyway bus/vboy updates: * Made slot probe software part to determine cartridge type * Made cartridges responsible for installing themselves * Added support for arbitrary cartridge sizes, assuming simplistic decoding * Added support for 8-bit and 16-bit SRAM on LSBs * Added support for EXP space and INTCRO output * Fixed SRAM not being loaded bus/generic: added a helper for mapping non-power-of-two memory with simple decoding cpu/v810: send I/O accesses to program space if I/O space is unconfigured vboy.cpp: updated for changed slot and CPU code bus/wswan: added notes The Virtual Boy software list is still in pretty poor shape. It's assuming all carts with SRAM have 8k*32, there are a bunch of feature tags for ICs that don't actually give an IC type, making them useless, 3-D Tetris mentions a battery but doesn't have an SRAM data area, Virtual Fishing refers to a HY6254ALLJ-10 which isn't a real part (I assume it means HY6264ALLJ-10 which is an 8k*8 50µA standby SRAM).

The cartridge effectively has three 16 bit 8 megaword (16 megabyte) read/
|
||||
write memory spaces. These are conventionally called EXP, CHIP and ROM.
|
||||
Only 16 bit word accesses are possible (no lane select signals, and no
|
||||
address bit A0). No commercial cartridges use the EXP space. The CHIP
|
||||
space is used for cartridge SRAM (if present) and the ROM space is used
|
||||
for program ROM.

|
||||
|
||||
Audio is passed through the cartridge, allowing cartridge hardware to
|
||||
modify it. The output of the Virtual Boy's VSU sound chip is DC-coupled
|
||||
to ARO (right) and ALO (left) via 4.7 kΩ resistors. ARI (right) and ALI
|
||||
(left) are AC-coupled to the Virtual Boy's audio amplifier.
|
||||
|
||||
VCC is +5V
|
||||
/INTCRO is an interrupt input from the cartridge to the host
|
||||
/RESET is bidirectional - the system or cartridge can pull it low
