In the case of the only(IIRC) HuCard to break 8megabits, SFII CE was 20 megabits (or 2.5 MegaBYTES) well beyond the physical address space of 2MegaBYTES) and HAD to reside in the lower HuCard address space (1MegaBYTE or 8megabits). So a game 8 megabits and under could use the entire lower address space of 8megabits or 1MegaBYTE for the HuCard never violating the upper memory address range used by hardware,etc. higan employs a unique user interface with the goal of providing the most faithfully accurate emulation possible, but as such, has a somewhat higher learning.
World Heroes 2 is the second game in the World Heroes series. Its codebase is intended to be self-documenting as the the original design of the hardware that it supports. Arcade, Neo Geo, Neo-Geo CD, PC-Engine Super CD-ROM², SNES, PlayStation 2, Wii Virtual Console, PlayStation 4, Xbox One, Nintendo Switch, NEOGEO Arcade Stick Pro. The upper MegaBYTE address space was mainly used for peripherals and hardware access. higan is a multi-system emulator focused on accuracy and preservation. Emulation SNK Emulation SNK - Neo Geo Pocket / Color (Beetle NeoPop) SNK - Neo Geo. The lower 1MegaBYTE was mainly for HuCard access( 1MegaBYTE = 8megabits). TG16/PC engine card games play fine in Launch Box but not CD games. Click to expand.The main cpu in the pc-engine(1987) and turbografx-16(1989) was a 6502/65c02 variant (HuC6280) with some extra cpu instructions for mapping banks of address space and some extra stuff.Īnyway, it was an 8 bit cpu with an 8 bit address space(64 KB) but with memory bank switching you could address 2 MegaBYTES of physical address space.
