/*
* UAE - The Un*x Amiga Emulator
*
* Save/restore emulator state
*
* (c) 1999-2001 Toni Wilen
*
* see below for ASF-structure
*/
/* Features:
*
* - full CPU state (68000/68010/68020/68030/68040/68060)
* - FPU (68881/68882/68040/68060)
* - full CIA-A and CIA-B state (with all internal registers)
* - saves all custom registers and audio internal state.
* - Chip, Bogo, Fast, Z3 and Picasso96 RAM supported
* - disk drive type, imagefile, track and motor state
* - Kickstart ROM version, address and size is saved. This data is not used during restore yet.
* - Action Replay state is saved
*/
/* Notes:
*
* - blitter state is not saved, blitter is forced to finish immediately if it
* was active
* - disk DMA state is completely saved
* - does not ask for statefile name and description. Currently uses DF0's disk
* image name (".adf" is replaced with ".asf")
* - only Amiga state is restored, harddisk support, autoconfig, expansion boards etc..
* are not saved/restored (and probably never will).
* - use this for saving games that can't be saved to disk
*/
/* Usage :
*
* save:
*
* set savestate_state = STATE_DOSAVE, savestate_filename = "..."
*
* restore:
*
* set savestate_state = STATE_DORESTORE, savestate_filename = "..."
*
