Re: Specasm: A Z80 assembler designed to run on the spectrum itself

Thank you very much for the continuously development and all the improvements!
When I add tools like the SERCP from PVYM and the (hex)EDITOR from NAMCO, it is a perfect system to do things without an emulator. :)

I recommend adding documentation to the distribution package.

Re: Some gigascreen game prototype: need input

Thank you for the enhanced software! This is the first full-screen gs. game for the classic ZX Spectrum! Before that, the gigascreen was mostly used for large static images or for parts of a game screen: maps in Gyron and Nether Earth. Maybe some part in the Soldier of Fortune is also diplayed by us...

The DataGear board used a Soviet clone instead of the real Zilog chip, and this had some differences... This is a wrong.

If I remember correctly (it was at least 10 years ago), in addition to a faster chip (from Toshiba), the content of the GAL is also modified (perhaps the same as for +3).
