Some time ago I asked about Commodore LCD on this list, but there was not so
much replies.  So I've decided to try to collect enough information using
various methods (disassemblying, asking people, tracing/debugging the code
with my own to-be-written emulator, etc) for two reasons: writing a
more-or-less correct specification and writing an emulator which can run the
original unpatched Commodore LCD ROM images.

Now after about a month of work, I have my own more-or-less working
Commodore LCD emulator (currently written in JavaScript) and some kind of
specification I managed to collect or find out myself, etc etc. Of course
the emulator itself is far from being really good, but still it's a start.

Many of the bugs are documented on the emulator page:

Also I've tried to create my own ROM to test fgx mode
and ROM scanning in general:

And the specification:

It's VERY IMPORTANT to thank for the help of some people:

And the main page in general:

Any feedback, suggestion, etc is welcome. No need to mention my
not-so-perfect English though :)
