gorilla-cpm's Issues

Conflicting Video Attribute Codes

I have found some conflicting tables on how the ADM-31 codes are implemented across platforms, the original ADM-31 decodes the char after the G as a bitfield:

0: Blanking or Underlining, depending on a DIP switch
1: Blinking
2: Reverse
3: Graphics

But the C128s implementation that you use in your game uses completly different codes that aren't decodable into a bitfield.
Maybe you could make a distinction between a real ADM-31 and the C128s implementation of one?

Attached for reference are the real terminals codes and (sorry, only found it in German from the book "C128 - Alles über CP/M 3") the C128s implementation.

Error to compile gorilla-cpm

I've tried to compile Gorilla using Turbo Modula-2 and both in YAZE and MSX-DOS (by OpenMSX) I've received the same kind of error:

>C
Compile file: main           
Imported: XTerm
FROM XTerm IMPORT SEQ,ESCAPE,AskTermType,ResetTerm,
                  ^   Error in Identifier:
XTerm.SYM not found

So I've tried to compile XTerm first but it still didn't find XTERM.SYM.

>C
Workfile name: xterm
FROM Strings IMPORT CAPS,Length;
^   Error in Identifier:
XTERM.SYM not found

There is a specific sequence to compile it?

Title should be "GORILLAS.BAS", not "GORILLA.BAS"

The original game was "GORILLAS.BAS", not "GORILLA.BAS".
How many gorillaS do you see in the game?
