[Coco] .BIN to .ROM

[Chad H]

Interesting about the 16K limit... How is it that the Arkanoid 32K ROM runs
on my CoCo 2?

The reason why we say the ROM can't be over 16K is the rompak eprom on a
Coco 1/2 can't be over 16K. ($C000 to $FEFF)  On the CoCo 3, a rompak can be
32k ($8000 to $FEFF) with the first 16K ($8000-$BFFF) not active till the
program switches to 32K mode.

There are some rompaks will more than 32K, but they use bank switching to
move ROM data in/out of the 32K address window of $8000 to $FEFF.  A regular
eprom does not have bank switching built in.

I'm still having a problem wrapping my head around the reason of trying to
put these files on a rompak?

Is it just about easy loading, DriveWire sure helps with that.

Or is it about replacing the Floppy Disk Controller (FDC) and Floppy drives
with something that's small and faster?  Well, there are a number of FDCs
emulators in for works for the CoCo.  They use SD Cards for storage and load
faster than a SCSI hard drive on a CoCo.  Best of all, they work with all
versions of DECB ROMs since the are hardware emulated and needs no software
modifications.
