Hey you!
Yes you!!!

Ever waned to try and write 6502 Assembly code?
Well then there is some stuff you'd like in this article

I might also make some posts about some things I make randomly on the site linked in the article aswell here on GJ.


There is plenty of ways to play around with the old 6502 prossesor, but I'd say that the best plase to try it for the first time is here
skilldrick.github.io/easy6502
There is a good amount of infomation on this page to really get to learn about the CPU arkitecture with not that much else to learn.

But if you'd like to go with just one text fuild to write code in, then there is a more cut down page from the same site
skilldrick.github.io/easy6502/simulator.html

Then there is the needed docs for every instroction the 6502 supports (only legal instructions work in the emulator)
www.masswerk.at/6502/6502_instruction_set.html

There is one thing the emulator won't tell you, that is it has support for hardcoding values/data using the Assembler directive DCB, it's only taking one byte at a time, but you can use it with multiple bytes sepperated with a comma (a byte holds a value from 0 to 255 or also writen as $00 to $FF)

#JoltShot

I've gotten my hand on a super gameboy, and I've all ready learned something about it that has made my program not display on the real thing

my old Hello World test program does though

I'm a bit late. but I got it now :D

I'm still learning all the new features past 1.13 of minecraft. but when we are talking of #MostFearedMob then that goes to the warden.

it's strong, can take your vision for a short time, it hits like a truck and it's purely after you when it detects you

I got my package. I got my package. I am excited

no more Oculus Rift S for me baby!!

Seams like the Linux version of the Gamejolt client has a flag set to addition while rendering on top of what's under the window. (it's just a guess, but it's what I get from this issue) hope it's possible to be fixed soon @gamejolt
