I am a geek. I play board games, build computers, assemble Legos, and play with old model trains

75.190Gigabyte ! In 2026 games are becoming ridiculously huge. Will the increase in RAM price make it more reasonable for the coming years?

yes Lego is expensive but it can be reused many times and it is passed from one generation to the next one. My son plays with old bricks I got from the 60s.

Merci. Je pensais Γͺtre le seul Γ  haΓ―r ce livre (mΓͺme ado l'idΓ©ologie dΓ©crite me rΓ©pugnait).
Quand on en a tiré une bd (parue chez Glenat) je me suis dit qu'une version plus moderne corrigerait les erreurs du roman mais (selon les critiques (je n'ai pas lu la bd)) la bd semble très fidèle au roman.

A space invaders game but all sprites are colored rectangles

A space invaders game but all sprites are colored rectangles

My Space invader tutorial begins to look like a real game.

I know the graphics are minimalists but I want the children to focus on the game mechanics, not on the graphics

Sometimes a bug in your software can create an interesting behavior

Like in this minimalist space invaders where the invaders move according a totally unexpected pattern

When You said (Source) Link, I was expecting a link to the source code of Eliza.

So Here is the code form de David Ahl book.

Just be careful: when you go from 6502 to ARM64:
1/ in ARM64, you must explicitely indicate 's' if you want to update the flags

2/ in ARM64 storing a register write 8 bytes instead of one byte (this is obvious but can be surprising: when writhing a char also write 7 zeroes in memory)

I think the code is simpler with LEDs because
1/ there is no timing critical issues
2/ there is only one bit per pixel
