Example of PHP and basic CRUD mySQL access. This is prototype hardware database I created for armchairarcade.com. It never got used but I was happy anyhow as I taught myself basic database PHP coding doing this. You can create and amend entries in a database, link screenshot images to an entry, and the "matrix" option is a simple reporting tool that lets you filter and sort the contents of the database.

Example of PHP web service. Click here For the documentation for a cocktail database and web service for use with mobile apps. Returns data in xml or json formats.

6502 assembler hacking. Atari 2600/VCS ROMS that I have amended to run full screen and full speed with PAL colours for use with the brilliant Harmony Cartridge and a PAL Atari 2600 console. (These will also run in the Stella emulator). Thanks to all at atariage.com for help with these - credit for some disassemblies and hints and help..etc (Nukey Shay, Spiceware, Debro, Thomas Jentzsch, Random Terrain and others)
Tools Used: DASM assembler, the great Stella emulator and debugger, Random Terrain's colour conversion tables, and Distella for creating my own disassemblies. I have provided links to the source code where I have created the disassembly myself from scratch. In these I have only commented code with respect to PAL & NTSC colour code conversions and the occasional change I had to make to the logic.
