Simply put, the most powerful user-friendly tool there is for creating games for 8-bit computers. A few formats (eg Spectrum, Amstrad CPC, Acorn Atom) currently supported, with more (Dragon, Acorn Electron, Enterprise) on the way. Create blocks, sprites and screens, knock out a few lines of code in AGD's simple scripting language (inspired by BASIC) or get the tool to create the code for you and create a Spectrum or CPC game that would have graced any software house's catalogue back in the day. Far more powerful than the original AGD with new commands and extra functionality, MPAGD comes complete with comprehensive documentation and example code templates. Includes tools to convert graphics between 8-bit formats, generating placeholders that can then be edited. MPAGD will even import 48K snapshots of games written using AGD 4.7 or AGDX and allow you to change or expand them. Games are output as assembler source files. Free to download with no obligations, I don't expect anything in return. However, should you absolutely insist on contributing towards the cost of a pint of beer go and buy one of my Egghead games or game development tools (Shoot-Em-Up Designer, Platform Game Designer) from www.cronosoft.co.uk
To get the best out of MPAGD, join the community of AGD and MPAGD developers over at the forums where help and support are available. There is a Facebook group and tutorial videos are available here:
If you're an experienced 8-bit developer and would like to add your favourite computer to the list of supported machines, get in touch.
Thanks to Kees van Oss for putting together the 32-bit version complete with build suites (hence the increased file size for that download)
