Here are the features of the Open ROMs not found in the original ROMs from the 80s (many of them are [configurable](CONFIG.md) during compilation):
* improved keyboard scanning, resistant to ghosting and joystick interference (one variant even supports multi-keyy rollover), supports additional C128 keys
* joystick can be used to move text cursor
* pre-defined function keys
* uses RAM under ROM and I/O: 61438 bytes free
* cold/warm start silences multiple SID chips - all $D4xx and $D5xx addresses, configured addresses
* warm start due to BRK prints out the instruction address
* JiffyDOS protocol support
* partial DolphinDOS protocol support (for now only LOAD is accelerated)
* DOS wedge (direct mode only) - `@<drive_number>`, `@<command>`, `@$`, `@$<params>`, `@`
* turbo tape load support (as device 7, or using `←L`), up to 250 blocks (can store bytes under I/O)
* extended `LOAD` command
* start/end addresses are displayed, in the Final cartridge style
* command with just the file name tries to use the last device if it's number seems sane; otherwise uses 8
* secondary address over 255 is considered a start address
* JiffyDOS protocol support
* turbo tape load support (as device 7 or using `←L`)
* DOS wedge (direct mode only) - `@<drive_number>`, `@<command>`, `@$`, `@$<params>`, `@`
* uses RAM under ROM and I/O: 61438 bytes free

NOTE: extra features and their syntax can change in the future!
