Description

=> The keyboard input in BASIC is broken, due to another update to scratch (and how it handles the keyboard). The other 2 Roms are games and should work fine. This is an Emulator of a (virtual) Computer with a MOS 6502 as CPU. It is similar to computers like the VIC-20 or the Apple I. Click on the ROMs on the left to load them. Snake and Kwirk are Games that I have written myself (in Assembly!). They are both controlled with the arrow keys. BASIC is derived from ehBasic by Lee Davison. -Enter a Memory Size (20000 should be enough), then use it like any other Basic interpreter. -Instructions here: http://6502.org/source/monitors/ehbasic/ehbasic.html -The left arrow will serve as a "Break-Key". -If you want to import instead of typing, press the 'Insert' Key. You can then enter a string, that will then be fed via the virtual keyboard. Any '§' in the string will be treated as a Return/Newline. Documentation and Tutorial on how to write your programs in assembly are over here : https://scratch.mit.edu/discuss/topic/282269 If you experience lag, try it with phosphorus: https://phosphorus.github.io/#175052082
