I've tested that it works in emulation. The only test left is the real deal my a Sega Master System.

# Cross-compiling directly to EEPROM
|

|

If your target media is a RAM mappable media, you can save prec-
|

ious RAM by cross-compiling Collapse OS directly to it. It req-

|

|

You can begin the process in a regular manner, but right before
|

you're about to assemble the boot code, take a pause.
|

|
||||
Up until now, you've been loading your cross compiling tools in
|
||||
RAM, now, you're about to write Collapse OS. So what you need
|
||||
to do is change HERE to the address of your EEPROM. Example:
|

|
||||
0x2000 HERE !
|
||||
|
||||
If you need to activate special system overrides such as the
|
||||
one described in doc/hw/at28.txt, now is the time.
|
||||
|
||||
Then, you can continue the process normally.
