  1. 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.
  2. 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.
  3. This bug is also discussed here:
  4. Putting in the better GC of C128 would not help since the bug is also in C128: "I found this bug in all versions of Commodore BASIC, that I investigated, VIC-20, C64, C128, C65, MEGA65." https://c65gs.blogspot.com/2021/03/guest-post-from-bitshifter-fixing.html
  5. Probably Luxor ABC80 from 1978: https://en.wikipedia.org/wiki/ABC_80 Then there was ABC800 from 1981: https://en.wikipedia.org/wiki/ABC_800 And ABC1600 from 1985: https://en.wikipedia.org/wiki/ABC_1600
  6. It would be interesting if someone could make a BASIC v2 program that demonstrates the bug in the garbage collector.
  7. I developed RatBAS2 in order to generate large BASIC v.2 programs from C-like source code: https://github.com/mobluse/ratbas2 RatBAS2 is similar to RatFOR (Rational Fortran). I discovered that RatFOR could be used to generate BASIC since it is similar to Fortran 66 and modern RatFOR has a disabled Fortran 66 mode that I could enable. RatBAS uses only IF...GOTO, but BASIC does have FOR...NEXT loops, ON...GOTO, GOSUB, and ON...GOSUB also. Unfortunately the program that turns a program in BASIC with labels into BASIC with line numbers doesn't handle the ON... constructs. FOR... NEXT is probably faster than using IF...GOTO.
  8. I think VAL() should work for hexadecimal numbers and not only for decimal as it does now. PRINT VAL("$FFFFFFF") should print: 268435455. I believe it would not be too difficult to implement since the code already exists for converting numbers in code. PRINT $FFFFFFF works now, and types: 268435455. Especially now when HEX$() exists in the next prerelease (-39). HEX$() converts without $ as prefix, but I think that's OK since $ could be added easily if one wants. It's also similar to how it works in other BASICs, e.g. GW-BASIC: http://www.antonis.de/qbebooks/gwbasman/hexs.html In GW-BASIC HEX$() also works for negative numbers, e.g. HEX$(-32768) is "8000", but negative numbers doesn't currently work with X16 BASIC HEX$(). I don't think it's necessary to implement VAL() for binary numbers, even though BIN$() exists, but if one did they should probably have % as prefix, e.g. %101. FreePascal uses the same prefixes: https://www.freepascal.org/docs-html/ref/refse6.html
  9. Is it legal to bundle the official rom.bin r39 from the Windows release (when it comes) in the snapcraft version of x16emu? because then the tests of release would work on more platforms that are not officially supported: e.g. for Linux with armhf and i386. https://snapcraft.io/x16emu
  10. "The KERNAL version can be read from location $FF80 in ROM. A value of $FF indicates a custom build. All other values encode the build number. Positive numbers are release versions ($02 = release version 2), two's complement negative numbers are prerelease versions ($FE = $100 - 2 = prerelease version 2)." - https://github.com/commanderx16/x16-docs/blob/master/Commander X16 Programmer's Reference Guide.md
  11. I believe it's only necessary with rom.bin, but you also included basic.bin, dos.bin, and geos.bin. When packaging for Linux according to the Makefile it only includes rom.bin. BTW I succeeded in building it for Raspberry Pi OS Buster on Raspberry Pi 4B and it works with all programs I tested with so far. x16emu_linux-armhf-2021-03-29.zip
  12. There is a flow control command in Applesoft BASIC that might be good to have in X16 BASIC: POP Removes one address from the return stack, i.e. converts last GOSUB into a GOTO. POP could be useful in more advanced BASIC programs. Maybe this could be solved using POKE, but it would be easier with a BASIC command, and then more old Applesoft BASIC programs could run on Commander X16. I did find two programs that uses POP: https://github.com/inexorabletash/jsbasic/blob/master/samples/sample.nuclear.txt https://github.com/inexorabletash/jsbasic/blob/master/samples/sample.pacman.txt https://www.calormen.com/jsbasic/reference.html https://www.landsnail.com/a2ref.htm
  13. In VIC20, C64, and X16 BASIC the AND, OR, and NOT operators are bitwise, but in Applesoft they are logical/boolean. 3=3 is -1 in X16 etc., but 1 in Applesoft. STR$(7) has an extra space for sign in X16 etc., but not in Applesoft. Applesoft is described here: https://www.calormen.com/jsbasic/reference.html X16 BASIC is the same as C64 BASIC (CBM BASIC v.2), but with enhancements: https://github.com/commanderx16/x16-docs/blob/master/Commander X16 Programmer's Reference Guide.md
  14. I could load the C128 program X16C128W70.PRG (above) in x16emu from the host file system using LOAD"X16C128W70.PRG" and LOAD"X16C128W70.PRG",8 but not using LOAD"X16C128W70.PRG",8,1. I've not tried to LOAD from SD card. Also I do not get the text "SEARCHING... LOADING FROM $..." but only "READY." Maybe you have a different release than 38 or this is how it looks when you load from an SD card. Anyway, I think loading should work in Commander X16 as in Commodore computers, because that is what most people expect and know how to handle.
  15. What do you mean would happen with the three line program where one line is skipped by linking in the cases ,8 and ,8,1 and x16emu -prg? I have two programs 3LINES.PRG and 3LINES2.PRG. The last is the hacked version where line 1 links to line 3. x16emu -prg 3LINES2.PRG and LIST gives two lines, but LOAD with ,8 and ,8,1 gives three lines in both x16emu and x64 from VICE. It seems that the program is repaired with both ,8 and ,8,1. 3LINES.PRG 3LINES2.PRG
