Hold my hand as I learn about C64 internals and 6502 assembly language while attempting to disassemble Jeff Minter's "best week of work I've ever done": the 1982 Commodore 64 classic, Gridrunner.

A lot of work went into this and I appreciate it.<p>After all, assembler is hard and every byte counts.<p>I remember a close friend of mine, co-founder of Success on C64 which later became Success&#x2F;TRC, did often time not clean up memory for some of his early demos before saving the final binary for crunching and spreading.<p>So you would have a lot of bogus code from other sources - games - in his works. Imagine a guy disassembling his stuff nowadays. ;)

I don&#x27;t think it&#x27;s the same person, but &quot;OldSkoolCoder&quot; streams a lot on twitch (<a href="https:&#x2F;&#x2F;www.twitch.tv&#x2F;oldskoolcoder" rel="nofollow">https:&#x2F;&#x2F;www.twitch.tv&#x2F;oldskoolcoder</a>) - a lot of disassembling and reverse engineering Jeff Minter games!<p>Another great resource if you&#x27;re looking to learn C64 assembler is <a href="https:&#x2F;&#x2F;www.twitch.tv&#x2F;shallan50k" rel="nofollow">https:&#x2F;&#x2F;www.twitch.tv&#x2F;shallan50k</a> (Shallan also has a great Discord server too).

This game is genuinely hard! You are really getting it from all sides at once. Can&#x27;t seem to get past Level 3. Any strategy tips would be welcome ;)

Jeff is one of my gaming&#x2F;programming heroes. Still doing great work today too.

so fun! reminds me of last christmas vakay when I was stepping through the execution of a c64 basic program in assembly. I was hoping to make a page like this. maybe this year :)<p>strangely AMC was one of hte few cartridges I had... Minter had a strange obsession with killer camels.
