Very cool. Last year I attempted to learn Morse, but I wasn't able to dedicate the time to it. I'll give this a shot. Now you can have another go with the morse "Challenge" game: challenge.jpg It looks popular at the local Makerfaire: makerfaire.jpg This Vic-20 is running the SuperVixen e...

Reopening the program, deleting the assembly and basic programs, then adding them again seems to have fixed something. Because then I got them compiled and put into the right locations... :shock: Before that, the assembly program would compile into the correct location, and it would simply stop with...

Never seen this before. Are other apps working properly? I had a quick google around and found this: Check to see if your Windows Display settings scale is set to the default of 100%. My scale is always set to 150% so I can read the display. At 100% its almost impossible for me to read it. I am als...

I have problems seeing dialog click boxes. E.g. I can't choose any options when the program gives me a message. In fact, I can't even start a new project for some reason: cbmprgstu.png So I revert back to an earlier version to see if that helps. Top menus are still overshadowing parts of the editor ...

The most silly program yet: Morse code keyboard morse.png Use the joystick fire button to tap Morse codes (as a real Morse coder) and see the output on the screen. It supports all letters but no numbers. Up to 4 segment morse codes. A half second space gives a space. 800Hz sound as real Morse codes ...

Rename the "minigrafik" file in Mike's download into "minigrafik.prg". Drag that into xvice. Then copy his basic code from the above post, change case into lower case and paste it into the xvice window (right click mouse in the window will paste it). Type "RUN" and pres...

My SD system as all done in code by an AVR, which was memory mapped to the rest of the system. Initialization was at 400KHz, and then I could speed up a lot more. Some cards faster than others. I never did settle on a top speed, ans planned to make some type of "auto speed detect" code to...

Great progress again! Are you going to fully implement FAT32? I would be interested in seeing that work as 6502 code. When I added SD to my other project, FS seemed like so much overhead that I ended up using RAW format, and made a PC program to write to the card as one giant 2GB binary. A simple f...

Some more updates: I decided to use IO2 area as a DMA buffer for the SPI interface for the SD Card. It has been quite hard to get this working, but I finally got the SDCard to respond. It may not look like much: SPIresponse.png What you see here are the actual signals on the SPI bus. At initializati...

Which was neither what it was aimed at. They reconstruct the upper three address lines for the expansion port, and they do so in a correct way. Repeating a wrong statement doesn't make it true. Eh? What is that supposed to prove. You can see that I checked all equations above. They produce the corr...

There are no BLK4, BLK6 or BLK7 signals on the expansion port Mike. For all expansion port memory areas, the equations are valid. Sigh. Your equations clearly aimed to reconstruct the values of the upper three CPU address lines, which they don't. Which was neither what it was aimed at. They reconst...

Obviously machine code is best but if you are results focused rather than an efficiency zealot, then C especially with a sprite library and memory expansion will get you comparable(ish) results much faster. I'd say it takes about 5+ times more development time in assembly compared to C. Also the co...

When the 6502 accesses BLK4 (except I/O 2 or I/O 3), BLK6 or BLK7, your equations fail.

i have a NEOS mouse here now....and i can tell two things for sure: - mouse cheese does neither use, nor even check, the left mouse button - the left mouse button IS connected to fire, just like vice used to emulate it (and i am right now putting that back into VICE) really curious now how you came...
