Robbo

This directory contains the source code of the 8-bit Atari game Robbo, created by Janusz Pelc in 1989 and published by LK Avalon.

Source files

Original program:

• d1/R1.ASM - main implementation, including also R2.ASM,
• d1/TITLE.ASM - title screen,
• d1/RS.ASM - saver utility,

Levels in txt format can be compiled by level-parser.go. Original ASM files can't be browsed in Github, because of the untranslated ATASCII characters:

• d2/C1: txt / ASM
• d2/C2: txt / ASM
• d2/C3: txt / ASM
• d2/DEMOL: txt / ASM

MADS files linking all the objects and producing executables:

• main.asm
• demo.asm
• saver.asm

Levels

For the levels, I introduced a custom text format, visually similar to ATASCII. It can be compiled with level-parser.go, original ASM files are available too and can be compiled with MADS. Replacing ATASCII characters in dta c'' with dta b() is not practical, as it'd make the design unreadable,
