r31767 Monday 25th August, 2014 at 11:15:32 UTC by Fabio Priuli

(MESS) a7800.c progress:  [Fabio Priuli] - Rewritten cart emulation to use slot devices - Removed POKEY chip from the main unit since it was inside  the carts (of course it gets enabled when you launch a game  who contained it in its cart) - Added support for the High Score cart as a passthru cart: when  you mount hiscore, a -cart2 switch will become available to mount  the game you want to play - Properly implemented XBoarD and XM expansions as  passthru carts as well, so that new syntax to run dkxm.a78 is  "mess a7800 -cart xm -cart2 path\to\games\dkxm.a78"  High Score support for XM shall work as well. - Big clean up of the driver, simplifying memory map, removing  writes to ROM, etc. Out of whatsnew: In conclusion, a7800.c has been brought into the new millennium ;-)

	4	Atari 7800 cart emulation

	6
	7	Emulation of the cartslot for Atari 7800
	8
	9	Quoting "ATARI 7800 BANKSWITCHING GUIDE" (by Eckhard Stolberg):
	10	7800 games can use the memory from $0400 to $047f, from $0500
	11	to $17ff and from $2800 to $ffff, but only the High-Score cart
	12	uses anything below $4000. It has 4KB of ROM at $3000-$3fff
	13	and 2KB of battery-backed RAM at $1000-$17ff.
	14
	15	Accordingly, we use the following handlers:
	16	- read_04xx/write_04xx for accesses in the $0400 to $047f range
	17	- read_10xx/write_10xx for accesses in the $1000 to $17ff range
	18	- read_30xx/write_30xx for accesses in the $3000 to $3fff range
	19	- read_40xx/write_40xx for accesses in the $4000 to $ffff range
	20	even if not all carts use all of them (in particular no cart type
	21	seems to use access to the ranges $0500 to $0fff and $2800 to $2fff)

8
9		14-May-2002 kubecj      Fixed Fatal Run - adding simple riot timer helped.
10		maybe someone with knowledge should add full fledged
11		riot emulation?
12
13		13-May-2002 kubecj      Fixed a7800_cart_type not to be too short ;-D
14		fixed for loading of bank6 cart (uh, I hope)
15		fixed for loading 64k supercarts
16		fixed for using PAL bios
17		cart not needed when in PAL mode
18		added F18 Hornet bank select type
19		added Activision bank select type
20		19-Feb-2010 DanB        Added return values for TIA collision registers
21
22		04-Apr-2014 Mike Saarna Fix to controller button RIOT behavior and
23		expanded cart handling (bit 05).
