device	pros/cons
Nintendo switch	runs linux, has MMU, is fast. But needs a payload via USB after each boot.
GPi case	runs linux, has MMU, but is quite slow, not good enough for SNES games?
Nintendo DS	runs linux 2.6 kernels, but needs RAM expansion over default 4MB. Low specs.
Sony PSP	Has no MMU, PSPlinux exists. PSP has low hardware specs thou.
Sony PS Vita	As os 2019 active development https://github.com/xerpi/vita-linux-loader, Vita has 512MB RAM
Rockpi4	more free, 6 core, raspi4
ESPboy	to weak for emulation
MiSTer	FPGA emulation introduction
Mega65	Aimed at being easy to understand
Steckschwein	Aimed at being easy to understand
Gigatron	Aimed at being easy to understand

FPGA (reprogrammable hardware) could be used.
- ULX3S, FPGA ESP32, WLAN, 32mb RAM
  - This one looks actually really really nice! Has USB, Wifi, Video out
- AndeShape FPGA boards, likely ~$1000
- iCEBreaker FPGA Development Board
  - Lattice iCE40UP5k FPGA, capable of hosting CPU soft cores such as picorv32, picosoc, and RISC-V
  - starting to ship for $69 on 2020-4-23
  - the board has no NIC
- https://www.crowdsupply.com/ has some interesting projects
KVM-guest on x86 can emulate RISC-V. Details from fedoraproject.org
HiFive Unleashed: to it's expensive.. currently at $999. I was looking for raspi scale performance wise.

2022 Dec: risc-v boards shown in oreboot auf RISC-V - Vergleichende Analyse zweier Implementierungen

Used Amiga 1200 or Amiga 600 are quite expensive.. how about making a nice case for retro computer emulation?

must have:
- provide space for a Raspi4 (ideally: a bit more space, for later upgrades)
- have a keyboard
- space for nvram or SSD, connected to the Raspi
nice to have:
- floppy drive, for Amiga disks
ideas:
- THE64 maxi: C64 original size, usable keyboard. But seems no longer produced, goes for 180eur, more expensive than C64
- original C64: I would destroy the case of a C64 then.. and I need a solution to connect the original keyboard to the Raspi. keyrah for 45eur can do that. But a keyboard with extra cursor keys would be nice.
- random keyboard with big case: Raspi might fit in there
- Amiga 1200 case: I would love that.. but where to get a keyboard. keyrah can also here do conversion to USB.
