Just because they’re both FPGA based products does not mean they’re equivalent. The Pocket can use its FPGAs to replicate dozens of different consoles and arcade units. It also has sleep mode and save states when using original cartridges.
Without adapters or OpenFPGA, the pocket can play GB, GBC, GBA original carts. With adapters, you can add in Neo Geo and Game Gear carts, and with open FPGA, you can add in NES, SNES, Genesis, Master System, dozens of arcade units, and dozens more I’m just forgetting. I personally have DigDug, Q Bert, and all the ones I mention above on mine.
The hardware alone on the Pocket is a massive upgrade over Funnyplaying, but when you include the OpenFPGA support, they’re not even in the same league. Not to trash the funny playing one, I think it’s great. It’s just not the same product category even imo.
Edit: sorry I misread.
No, what he shared cannot do most of that. It can play game boy cartridges though.
