X16&C64 Keywords & Abbreviations Quiz View File This game quizzes the player about the abbreviations for the Commander X16 BASIC v2 keywords. If you know these abbreviations you can code BASIC for X16 and C64 faster and write more code per line. First the program figures out the keywords and abbreviations for the exact release of the ROM. Then you are offered the quiz. The quiz is timed and the errors are counted. If you give the wrong answer you get that question again directly. C64 mode: You can stop the program by pressing the Esc key before the quiz, then type SCREEN 255:RUN 64 and press Enter to only be quizzed for C64 keywords. The game X16&C64 Keywords&Abbreviations is tested with R38 (Try it now) and R41, but may work with later releases. The program is FOSS (license GPLv3) and the source is included in the zip-file, but is also on GitHub: https://github.com/mobluse/chargen-maker Command line: x16emu -bas KEYWORDSABBR.BAS -run -echo By using -echo you can copy the generated program and load it in x16emu and check that the abbreviations really expand correctly.

So, I came across this recently: https://www.youtube.com/watch?v=ROR1NQE-2DY "VisionBASIC", a compiled BASIC for the C64. Note that to write and compile programs in VisionBASIC you need extra RAM - but it's compatible with many forms of RAM expansion, not only vintage solutions like old REUs or the SuperCPU, but also modern ('retro') gear like the Turbo Chameleon or either of Gideon's "Ultimate" producrs (the cart, or the Ultimate C64 itself). Or even just in an emulator. ....but, crucially, you don't need the extra RAM to run programs compiled with VisionBASIC. So you can use it as a developer, but still distribute your work and expect it to run on stock C64s.

On the C64 we could clear line X on the screen using a poke and sys to a kernal function. POKE 781,X: SYS 59903 Is there something like this for the X16? If I try it, it simply clears the entire screen. What I am doing is printing a game "shopping list" using CHR$(!13) CHR$($11) CHR$($11) so in the middle of the screen is a table of items. Then I'm using CHR$($13) to send the cursor back to home and prompt what the player would like to buy. The 2nd line would say if they purchased it, didn't have enough money, etc. Then I was hoping to clear just the 2nd line on the screen and re-prompt them until they leave the store. Any pointers would be cool.

Considering how many of the Commodore 64's part just die of old age, it's been a joy to see people creating very good modern replacements for problematic chips (PLA, SID). I learned today of someone working on an FPGA replacement for the VIC-II. Here's the video

Welcome back ...

I wanted a CRT for my retro computers, but I didn’t want to deal with the weight and the size... so I found a 6 inches TV/radio combo for sale, that has video and audio input, and it was cheap! (€10, around $12). i’m really happy with my purchase, and thought you guys may appreciate it.

C64 image file viewer (koala format) View File I wrote a program that loads Commodore-64 multicolor pixel art images in the "koala" file format, and displays them to a regular Commander X16 320x200 graphics screen. The C64 uses a fixed palette of 16 colors for all its graphics. I do find that the saturation of the default colors in de c64 palette in the Cx16 emulator is not very good though: when the images are displayed on a C64 or in an emulator like Vice for instance, they look much better in my opinion. So the program sets a custom palette (the "pepto" Vic-II colors) to make the images look closer like they would on a C64. This program has been integrated in a multi-format image viewer now, the source code of that is here https://github.com/irmen/prog8/tree/master/examples/cx16/imageviewer Submitter desertfish Submitted 12/02/20 Category Demos
