If you are interested in BASIC programming for the C-64, then you have probably used a BASIC Extension at some point.  Most of us are familiar with Commodore’s Simons’ BASIC cartridge.  Unfortunately, most of these extensions aren’t very useful.

Simons’ BASIC, for example, has a pretty lousy set of commands.  Many of them are basically (pun) useless.  It’s also a very confusing set of commands — there are no consistent conventions used, making it necessary to constantly refer to the manual.

Further, a program written with Simons’ BASIC can only be run on a C-64 with a Simons’ BASIC cartridge.  Pretty limiting. DotBASIC Plus is similar to other extensions in one way: you get a lot of new commands (or DotCommands, of course) — over 100 so far.  But that’s where the similarities end.

Char Pad is a cross-development tools aimed squarely at developing graphics for Commodore 64 games and will hopefully ease and inspire the production of new games software for this immortal and unique platform.

New features:

• Variable tile sizes, currently 1×1, 2×2, 3×3, 4×4 or 5×5.
• Pixel level editing of whole tiles.
• 80×50 and 40×25 map editor modes.
• Map flood-fill + copy & paste any map area.
• Move & Mirror tiles or maps.
• Powerful character set optimizer.
• Collision “material” editing & grouping for easy software collision detection.
• Export any data in raw or PRG formats.
• Load and save SEUCK compatible background files (including Jon Wells’ sideways SEUCK mod).
