if it's mouse compitable it's usb lightgun compitable, the usb-lightguns are or an air mouse (gyroscope, or ir tracker mouse, it will always send signals like a mouse does.
it's nice it's opensource, but as for this time it doesn't add anything that is really new to the market except that it's a opensource multi-rom loader.
i don't see anything special as long as it requires illigal handeling of cardridges, i don't see anything new as it's not doing even it's best to be accurate to the system... anyone can run the games by now as it's designed, and FPGA isn't that special as it is proclaimed.
so the real question is and should be, why a hype for a retropy 4x the size?
I'm not really sure you understand what this is, especially with comments like:
Now there are discussions which can be made over the merits of FPGA vs software emulation, but FPGA is not software emulation and ARM is a CPU architecture, not an FPGA (although it might be implementable on one).
MiSTer is not new, it's an open source 'standard'. The merits of the device in the OP is entirely dependent on whether you want to make a MiSTer system in a relatively simple way.
FPGA is a little different then arm, at my work it's common used, alright arm is a cpu driven by the bootloader, cpu, etc etc, and fpga is a programmed IC closer to hardware since it's not depending on external hardware to function...
the FPGA is still programmed like raspberry py with linux background and the emulation cores now hard loaded to the FPGA, it's still not really doing anything new, it's still gonna act like the raspberry py, only raspberry pi won't load the emulation core into real hardware, it loads it from the emmc/sd-card.
big deal.
if the cores are not acting as the original cores of hardware but as an emulator, it's not anything special.
i know it's impressive how many people are involved, and i see some special roms working on this so called hw emulator.
till this point and i have the feeling this is a hard one to go around, it's emulating the software through FPGA wich had the power to emulate it hardware like.
if it's emulating snes like it's been done in snes9x i couldn't care how beautifull the hw is, it's still a waste.
sure snes9x gets about all the snes roms going, and yes there's going to be a lot of more emulators.
but it's not ever bringing back the original feeling, nor is it adding new features.
and since in most countries today it's illigal to make your backups in a way not described by thier original creators it's also going to force me into using a grey area of legal use.
and thanks, i see i misted out what it was all about, not the mister part bu the board underneath, witch adds RAM, expansion slots, scart, optical out, HDMI and USB.
and again great to see the work. what does it really add to the market of retro consoles other than opensource FPGA illegal large retropie like system?
