  1. It says "support for ON ... GOTO N1, N2, N3", but does it also support "ON ... GOSUB N1, N2, N3"?
  2. You can paste in data in iAltair from e.g. an email. You might request that the developer includes extra software such as fig-Forth. It is difficult to export data, but you can take screenshots and run them through OCR.
  3. The X16 has a IEC compatible (Commodore) disk drive port. Would it be possible to also send video from this commodore serial bus on the X16? That means you could have an extra screen to the X16.
  4. There is a CP/M computer emulator for iPhone (and probably iPad): iAltair https://apps.apple.com/se/app/ialtair/id291182085 More documentation: https://schorn.ch/ialtair.html It's possible to use this with a Bluetooth keyboard (but it also works with the screen keyboard) and to paste in text from the iPhone's clipboard. One can also save to the built in diskette. BTW The CP/M for V20 and V30, mentioned above, using the 8080 mode is called 22nice.
  5. It might be possible to write a CP/M 8080 emulator for X16, just like there exists one for C64, which I tested some years ago. I tested the following 8080 emulator with CP/M on Raspberry Pi in 2014: https://nanochess.org/emulator.html This source code is rather difficult to understand, but one could write an Intel 8080 emulator from scratch that has the same instructions for peripheral operations and then the rest of the files should work. Not all CP/M software works on 8080 since Zilog Z80 was more common. I have PCs with V20 and V30 CPUs (80186 super set) that can emulate 8080 in hardware and there was also CP/M-80 for PCs that used that 8080 emulation. My Amstrad PC1512 had originally 8086 CPU, but I switched it to V30. I found a tutorial on how to write an 8080 emulator: http://emulator101.com/
  6. When do start measuring the time? Is it from start of program or e.g. from when OXYGENE is shown? It is a bit faster on second run: about 68% of full speed on my computer.
  7. I got it to run on my computer with dual core x86-64 and Windows 10 using: ..\x16emu_win-r38\x16emu.exe -ram 2048 -run -prg STNICCC.PRG Unfortunately my computer is not that fast so it only run in 50% speed. It said the time was 1:39.96, but it was longer in reality.
  8. I have updated the PETSCII: x16emu: 5 SCREEN0 10 ?CHR$($A5);CHR$($A7) VICE x64: 5 ?"{clear}"; 10 ?CHR$(10*16+5);CHR$(10*16+7) There seems to be an error in the X16 ROM for CHR$($A7) because it is not just thinner, but in the wrong end compared to C64.
  9. From the release notes for r38: "changed PETSCII screen codes $65/$67 to PET 1/8th blocks" I don't see any difference between X16 and C64. I tried this code in x16emu: 5 SCREEN0 10 ?CHR$($65);CHR$($67) and this in x64 in VICE 3.4 SDL2: 5 ?"{clear}"; 10 ?CHR$(6*16+5);CHR$(6*16+7) ({clear} is Shift+Home i.e. a reversed heart.) What is the difference between the C64 character set and X16? I think it's good if there are identical characters in C64 that they are different in X16, because there is no point in having identical characters. It is a problem of how to print them since the Style64.org PETSCII font probably only supports C64.
  10. I use GNU Nano as my main editor in Linux and I noticed a disadvantage of Ctrl+U (Uncut) in X16 Edit: Ctrl+U can only paste once in X16 Edit, but several times in Nano. I hope this will change because I often use Ctrl+U several times in Nano and would like to do so in X16 Edit. I believe there is no advantage of emptying the cut-buffer after the first uncut/paste.
  11. I think this is great. Does it handle labels in ON...GOTO and ON...GOSUB? How do you enter the BPP files? since the built in editor requires line numbers.
  12. There are emulators for other computers that run in a terminal e.g. https://atari800.github.io/ and http://rullf2.xs4all.nl/sg/zx81ce.html. The output of x16emu can be sent through a filter program that converts PETSCII to UTF8: https://github.com/mobluse/x16-petscii2utf8 The difficult thing is to get the keys you press (key down and key up events) in the terminal to be sent to x16emu. I once hacked x16emu so that this was possible, but that slowed down the emulator. One would also need to remove the GUI to make it independent of X and SDL.
  13. I tested my game Aritm using the "Try it now" feature in Chrome on iPhone 8 Plus and it works well, but it requires a Bluetooth keyboard since the web emulator of CX16 doesn't have a screen keyboard and the phone's own touch keyboard doesn't come up. If I click outside the CX16 screen and scroll and return, the Bluetooth keyboard stops working, even if I touch the X16 screen. If I then touch the close button (X, actually a zoom out button) and then go full screen again the Bluetooth keyboard works again in the Commander X16 emulator. Another issue (that isn't only for phones) is that the speaker mute button shows as muted from start, but there is sound (e.g. if you enter wrongly in Aritm) from start. If you toggle the mute button a couple of times then it shows correctly the same way as on e.g. YouTube. (It can be difficult to type "-" (minus sign) on some international Bluetooth keyboards, therefore I've added "." (point/period/stop) as an alternative to minus. Actually, this alternative has existed for a long time since I had this problem in other emulators too.) Maybe @SebastianVoges can help.
  14. The title in Featured Downloads is overlapped by the name of the developer. This is so in all browsers I tested this in: Chromium, Vivaldi, and Firefox in Raspberry Pi OS. If I press Ctrl+- twice I get zoom 80% and then it doesn't overlap, but that makes the text too tiny. I have 1280x1024 pixels screen.
  15. This bug is also discussed here:
