Re: GALAXY GAME!!! :D :D :D

First of all thanks for your hard word on OCR-ing original PDF listing, it made Galaxy Game driver possible.

T11 is good enough for the driver at this point, when PDP-11/20 is emulated (which may happen on MESS side), driver may be switched to use it.

I'm loading code from compile code listing (taken from your site actually). I guess it is best option now, as it allows source code to be preserved, while still loading compiled code from it.

About the bugs: I assume you are referring to these:
1006 006432 006601 10060 ROL R1
1007 006434 006602 10070 ROL R2
These are now patched during loading to use correct ROL opcodes.
If there are more bugs in original listing which you fixed then, please let me know.

Mariusz.
