Spectrum Computing

The decompression routine is very slow, but it compress better than exomizer. That converts to the perfect compressor for 4K demos. The original code is from here:

I have Windows and I can't try.

puts machine code inside BASIC loader. What assembler do that?

*(int*)(mem+3)= 0x8e117d06; *(int*)(mem+7)= 0x0e37c0fd; *(int*)(mem+11)= 0x2196398f; *(int*)(mem+15)= 0xb8edda6d; *(int*)(mem+19)= 0xe9f9eb13; The hidden assembly code is: l5ccb: ld b, $7d ld de, $fd8e defb $c0, $37, $0e, $8f, $39, $96 ; paolo ferraris method, in basic jump to $5ccb l5cd6: ld hl, $...

I did. You can compare:

• rect_tap8k.tap is 70 bytes, 10 seconds to load
• rect_pasmo.tap is 146 bytes, 20 seconds to load

I can not attach the .zip but you can see at this image.

Write a simple TAP using Pasmo and let's compare. I am sure with tap8k the loading time (and filesize) is almost half. Pasmo already generates .TAP files, and you can simply concatenate a binary output with a pre-defined basic loader.TAP. What specific case does it solve ? Looking at the code, it se...

I did this tool that can be useful. It generates a .TAP with only the basic block from a binary file (assembled with .org 32768). It's good for small games or tests (because you don't have loading screen). https://github.com/antoniovillena/zx7b/blob/master/tap8k.c https://github.com/antoniovillena/z...
