ZXSpectrum

ZX Spectrum Bare Metal Code by krom (Peter Lemon).

All code compiles out of box with the bass assembler by byuu.
I use a special version of bass by ARM9 which has been updated with ZX Spectrum Z80 output:

I have included binaries of all the demos.

I also use a tool called Image Spectrumizer, which I use to convert GFX to the ZX Spectrum screen:

Special thanks to Dobo/spec-chum, who has helped me get into ZX Spectrum Coding =D

Howto Compile:
All the code compiles into a single binary (TAPENAME.Z80) file.
Using bass Run: make.bat

Howto Run:
I only test with a real ZX Spectrum 128+3 using the fast disk upload tool Project OTLA:

You can also use ZX Spectrum emulators like Speccy & the MAME ZX Spectrum Driver.
