:: Client-side ROM and state storage to save bandwidth and solve the legal hurdles of an online emulator.
:: Proper emulation of interrupts, flash, hardware quirks, LCD latency, and other attributes of the real hardware.
:: Skinned and unskinned mode
There are also many planned but as-yet unimplemented features:
:: Integration into the SourceCoder online TI-BASIC IDE, including importing/exporting SourceCoder projects to/from jsTIfied.
:: globalCALCnet (gCn) support
:: Importing/exporting programs, files, and apps to the user's hard drive
:: Loading files directly from the Cemetech/ticalc.org archives.
I hope that you'll give jsTIfied a try as soon as possible, give me feedback (especially when run in browsers other than Firefox), and enjoy! Note: remember that distributing ROMs is illegal. Do not ask for or offer ROMs to any other members, on the forum or privately.
