Just read a post on the WOS forums from Gasman who says that he's just released v2006-05-17 of his OpenZXRom project. If you don't know already the idea behind it is to create a complete Open Source ROM, compatible with the original ZX Spectrum ROM, but containing only new code - the result being it can be used in new hardware projects. This latest version has reached "an important milestone - it now replicates enough ROM routines to play Egghead 4 and The Fantastic Mister Fruity. Yay!"
Yay! indeed.
And can I just say I like the version numbering system. It will work great providing the developers don't do anything stupid like release two versions in one day.
