Uxn32 1.8

> Download Uxn32 1.8 + Essentials ROM pack

It's time for a new release. A few small bug fixes, a few small behavior changes, and a fresh pack of ROMs.

• Updated the bundled ROMs to freshly baked versions.
• Uxn32 windows will now have a minimum size, so that you can't accidentally resize a window too small and cut off some of the virtual screen area.
• The virtual screen in Uxn32 windows will now scale to 3x and beyond, if the window is large enough.
  • Toggling zoom with F1 will still only cycle between window sizes to match 1x and 2x, though.
• Fixed the PC (program counter) being set to 0 in a duplicated window.
  • This was noticeable if you duplicated a window while the program was frozen mid-execution with Beetbug. And now it's fixed.
• Fixed Beetbug swapping the mnemonics for OVR and DUP opcodes.
  • Oops. This mistake was added back when the opcode values were shuffled earlier in 2022.
• Added special-casing to Beetbug so that instruction 0x00 displays as BRK, and LITk displays as the less-noisy (but equivalent) LIT.
  • You can also enter these mnemonics as input in the Beetbug memory editor.
• Changed 16-bit PEEKs and POKEs operating at address 0xFFFF to not wrap the higher byte back down to address 0x0000.
  • Instead, there's now a secret padding byte after 0xFFFF that will absorb the extra byte. Shhh, don't tell anyone.
  • This was done to match the behavior of uxnsdl.
• Added handling of the .System/state (0x0F port)
  • When a Uxn program writes a byte to it, Beetbug will open and say that the program requested exit.
  • Because it's not normal for Windows GUI programs that are emulating some other system to vanish without the user closing it, I chose this behavior instead.
  • This might be a bad idea, so it might be changed in the future.

(Edit - Uxn32.exe was accidentally named Uxn.exe. Fixed, and updated the .zip as well. Sorry about that!)

Uxn32 1.7

> Download Uxn32 1.7 + Essentials ROM pack

This release is for ROM updates and bug fixes.

• Update the bundled ROMs to freshly baked versions.
• Fixed mousewheel events being dropped when the mouse is in the bottom right quadrant of the screen, and also in multi-monitor desktops.
• Fixed a bug where a 16-bit read or write instruction to address 0xFFFF would have the second byte read or write 1 byte of additional memory at nonexistent address 0x10000 instead of wrapping and operating at address 0x0000.

Uxn32 1.6

> Download Uxn32 1.6 + Essentials ROM pack

• Shuffle the CPU opcode values around to match the shuffling that the main uxnemu project did.

  • This means that Uxn32 1.6 and onwards (and uxnemu) is incompatible with older ROMs, and newer ROMs are incompatible with older versions of Uxn32 (and uxnemu.)
  • Mismatched ROMs will fault and cause Beetbug to open. The Uxn ROM format doesn't have any version tagging, so there's no way to detect this when opening the ROM.
  • The ROMs bundled with this release of Uxn32 are already updated to work correctly.
  • If you made any of your own ROMs, you will need to recompile them with the newer assembler (included in Uxn32.) You probably won't need to make any source code changes.
  • Sorry about that. This decision was made by the uxnemu project (mailing list email here), and Uxn32 has to change to match it, otherwise they will be incompatible going forward.

• Add second 'File' virtual device. (This matches a change in the main uxnemu project.)

  • Like the change above with the CPU opcodes values, this also implies a breaking change, though to a lesser degree. Some ROMs may have continued to work without being recompiled, and some may not.
  • If you used the datetime device in your program, you will need to update your source file so that has the new address:
    • |b0 @DateTime … becomes |c0 @DateTime …
  • Fortunately, both of these breaking changes happened in the same release.

• Change to automatically balance the stack with 0xFF when breaking into Beetbug after a division-by-zero fault.
