None of this modern multi-core rubbish or branch predicting exploitable nonsense here. Just you, me, DOS and a C compiler. #MSDOS #DJGPP #CProgramming #AssemblyLanguage https://beta.ncot.uk/videos/exploring-hardware-hacks-joystick-integration-keyboard-inputs-and-debugging-with-the-agon-light/ Sat, 24 Feb 2024 15:13:25 +0000 https://beta.ncot.uk/videos/exploring-hardware-hacks-joystick-integration-keyboard-inputs-and-debugging-with-the-agon-light/ Dive into the exciting world of DIY hardware hacking. Join in as I explore joystick integration, keyboard inputs, and serial debugging using the versatile Agon Light platform. Delve into the technical intricacies of GPIO pins, assembly language programming, and C compiler usage for low-level development.

It is the same for our simulator #CoreWar #AssemblyLanguage #Programming https://beta.ncot.uk/blog-posts/how-to-write-emulator-opcodes-jumptables/ Sat, 07 Dec 2019 22:01:36 +0000 https://beta.ncot.uk/blog-posts/how-to-write-emulator-opcodes-jumptables/ How to efficiently store and execute many small functions, without using a single if statement or switch construct. #CoreWar #AssemblyLanguage #Programming https://beta.ncot.uk/blog-posts/how-to-write-emulator-intro/ Sat, 07 Dec 2019 21:41:24 +0000 https://beta.ncot.uk/blog-posts/how-to-write-emulator-intro/ To begin, this isn’t technically an emulator, the system I’m trying to model isn’t real. This is more of a simulator, but that’s less of a catchy search word on the Internet. #CoreWar #AssemblyLanguage #Programming
