support to replace CBM channel and editor code with GPLed 'open-roms' code by the MEGA65 project.

separated KERNAL code into core code and drivers.

enabled partition types 0x0b and 0x0c, should accept more image types.

TI is independent of TI$ and can be assigned.

TI$ and DA$ (DATE$) are now connected to the new date/time API.

support for VERA 0.9 register layout (Frank van den Hoef).

new entropy_get API to get randomness, used by FPLIB/BASIC RND function.

new: console_set_paging_message (to pause after a full screen).

fixed access to paths with non-ASCII characters on Windows.

added -abufs to specify number of audio buffers.

YM2151 support is now enabled by default.

The VERA UART has been removed from the emulator (FPGA constraints).

See the VERA Programmer's Reference for details:

BREAKING CHANGE: The register layout of the VERA graphics chip has changed significantly.

YM audio enabled by default in the emulator.

Emulator support for VERA PCM and PSG audio.

detection of SD card presence, fallback to Commodore Serial.

almost complete set of commands ('scratch', 'rename'.

long filenames, full ISO-8859-15 translation.

set-position support in PRG files (like sd2iec).

new 'modify' mode ('M') that allows reading and writing.

rewrote most of DOS ('CMDR-DOS'), almost CMD FD/HD feature parity.

switched to FAT32 library by Frank van den Hoef.

changed PETSCII screen codes $65/$67 to PET 1/8th blocks.

fixed STOP key when showing directory listing ( DOS'$').

like LOAD/SAVE, OPEN now also defaults to last IEEE device (or 8).

updated power-on logo to match the real X16 logo better.

ported over INT(.9+.1) = 0 fix from C128.

optimized addition, multiplication and SQR.

fixed screen_set_charset custom charset.

LOAD on IEEE without fn defaults to ':*' changed F5 key to 'LOAD'.

hacked (non-functional) Commodore Serial to not hang.

load uses macptr for LOAD speeds from SD card of about 140 KB/sec.

new macptr API to receive multiple bytes from an IEEE device.

Various WebAssembly improvements and fixes.

zero page register display in debugger.

expose 32 bit cycle counter (up to 500 sec) in emulator I/O area.

added warp mode (Ctrl+'+'/Cmd+'+' to toggle, or -warp).

improved/cleaned up SD card emulation.

Ctrl+D/Cmd+D detaches/attaches SD card (for debugging).

added VERA dump, fill commands to debugger.

added WAI, BBS, BBR, SMB, and RMB instructions.

See x16-emulator README on how to mount it on Mac/Linux/Windows, and CMDR-DOS README for the supported DOS features. You can attach an SD card image with -sdcard there is a sample image in.

ROM: full-featured DOS implementation (SD card).
