Already implemented

• 8Mhz CPU for ST and STE modes
• 16Mhz CPU for Mega STE mode
• ~48MHz CPU for STEroids mode, roughly as fast as a TT
• Up to 14MB fully DMA supported and video capable ST RAM
• ROM cartridge support
• Support for 256k and 192k ROM images
• TOS versions 1.00, 1.02, 1.04, 1.06, 1,62 2.06 and EmuTOS 0.8.7, 0.9.0 and 0.9.1 and probably more ...
• All three ST video modes
• SM194/Viking compatible 1280x1024 high rez video mode
• Scan doubler for color modes for VGA compatibility
• PAL 56 HZ for VGA compatibility
• Floppy disk emulation via SD card (.ST formats incl. HD (1.44MB) and ED (2.88MB))
• AHDI compatible ACSI/HDD emulation via SD card using Hatari compatible ACSI images
• MFP (Timers, RS232 redirection, IRQs, ...)
• Sound
• IKBD emulation (joysticks, mouse, keyboard)
• USB mice, keyboards and joysticks
• Printer/RS232/MIDI redirection to a PC connected via USB
• Ethernec compatible network using DLink DUB-E100
• Minimig on screen display (OSD)
• Ability to change the core (to e.g. boot into Minimig)
• MIDI add-on board
• Blitter (Optional for ST, mandatory for STE)
• STE video (4 bit per color, hard scrolling, split screen, ...)
• STE DMA sound

Planned/Possible

• More extended video modes (e.g. 640x480 @ 16 colors, 1024x768 @ 4 colors)
• 16MB fast/alternate RAM
• Support for STX (copy protoected) floppy disk images
• USB floppy disk drives, memory sticks and hard drives

Frequently asked things that will most likely never happen

• Falcon compatibility (This requires a DSP and various other complex things that don't fit into the MIST FPGA)
• 68040/68060 add-on board (the MIST doesn't have enough spare IO pins for this)
• 68040/68060 FPGA implementation (the MIST FPGA is too small for this)

Summary

Mega STE and more has been done, parts of a TT are also done but full TT compatibility is very unlikely and Falcon (incl. e.g. DSP) is impossible
