@ -26,17 +26,20 @@ As with many emulators, you have to go get the ROMs yourself. I've got
the ROMs that I dumped out of my Apple //e. You can probably get yours
a lot easier.
There are three files that you'll need:
There are four files that you'll need:
* apple2e.rom -- a 32k dump of the entire Apple //e ROM
* disk.rom -- a 256 byte dump of the DiskII controller ROM (16-sector P5)
* parallel.rom -- a 256 byte dump of the Apple Parallel Card
* HDDRVR.BIN -- a 256 byte hard drive driver from AppleWin
(https://github.com/AppleWin/AppleWin/blob/master/firmware/HDD/HDDRVR.BIN)
The MD5 sums of those files are:
* 003a780b461c96ae3e72861ed0f4d3d9 apple2e.rom
* 2020aa1413ff77fe29353f3ee72dc295 disk.rom
* 5902996f16dc78fc013f6e1db14805b3 parallel.rom
* e91f379957d87aa0af0c7255f6ee6ba0 HDDRVR.BIN
From those, the appropriate headers will be automatically generated by
"make roms" (or any other target that relies on the ROMs).
