I made a paper backup of the code. Four A4 pages per game (single side).

Works perfectly smooth on EeePC class CPU.

For anyone intrested in boot sector programming this is the best tool out there!

I was searching so long for anything close to this for days. And bum! I don't even remember where I found it.

=> https://www.bootsector.games/

• x86 BIOS Emulator
• Assembly IDE (bad error handling)
• Compiler, Debugger, Stepper
• Live memory map! <- this is HUGE for me
• Web only (Good and bad)

Yes!

My first boot-sector game is done!

Your goal is to fall into the moving boat at the bottom. Do not touch red platforms or fall into the ocean.

It has four levels.

All 512 bytes used!

Removed super nice animated sprite of the player for more space.... This enables me to implement:

• restart game
• exit platform to go to next level
• dying restart to first level
• 4 levels (last 2 empty in video).

504 bytes

State of the game.

• The dude has 3 frames to save space
• Simple gravity added
• Key-press changes his movement direction
• Dude cant go outside the screen

359 bytes used of 512b limit.

This 12-byte program composed of pure x86 machine code writes itself to standard output:

What a productive Saturday!

Continuing from my crack of SimCity 1.02, I did the same for 1.07 plus made a cracking program and a trainer for it, both written in assembly.

The trainer started out as a TSR (my first TSR!) but is now a "direct loader" instead, so it executes SIMCITY.EXE for you.

Pressing F1 gives you over $2 billion, done by hooking a keyboard interrupt vector, which is also a first for me.

Now I just need a cool cracker name (suggestions welcome) and a cracktro :D

This is a very clear, understandable, introduction to 6502 object linking! https://www.youtube.com/watch?v=0q6Ujn_zNH8 #asm #retroprogramming #retrocomputing

Is it called the carry flag because I carried it for 13 instructions! XD #z80 #asm #retroprogramming #retrocomputing

kroc, 5 months ago to retrocomputing

This won't necessarily be easy to understand, but my word is it a work of art! https://github.com/Kroc/v80/blob/d54b67927304971fc01cac6e1aefeaf7abf4e623/src/v80.wla#L291-L369
Symbol search; uses a linked list. Compares name lengths and then strings.
Using the remainder of BC from CPD (compare-and-decrement) to snap back from the middle of a string to the link-addr is neato #z80 #v80 #retrocomputing #asm #cpm

I literally couldn't find an example of reading ASCII hex digits and converting to a number in #Z80 on Google or DDG!?? Had to write this myself, but I think it's novel with the bit 5 trick. Is there a better way to do this? #asm #programming #RetroComputing

alrj, 5 months ago to asm

When I was pondering whether to add some special challenge to the #adventofcode this year, I was more thinking about doing it on a #retrocomputer like my 486, or solving some puzzles in #asm.
Not doing them completely ill with high fever.

Stack management systems of Goroutines and PHP Fibers seem to conflict and sometimes crash: https://github.com/golang/go/issues/62130

Does anyone have an idea of what's going on?
