Recently, I bought a Taito Super Pocket, a small vertical handheld that plays a bunch of Taito arcade games, because it felt like the sort of thing I'd be all for at the asking price of £50, and I apparently have poor impulse control. The main party trick of this handheld, compared to the dozens of sub-£50 emulation handhelds you can find on Aliexpress that all run some Retroarch frontend and feature the same shoddy bootleg roms on a dubious SD card, is that it happens to take Evercade cartridges.
Now, Evercades are a thing I've always been at least somewhat aware of but I... largely ignored them in favour of aforementioned Chinese Original emulation devices. This was probably a mistake. Mostly for the novelty of the option being there, I picked up a couple of cartridges - Renovation Collection and The Oliver Twins collection; in the space of a week I have completed the Mega Drive versions of Valis I and III, the Mega Drive version of Sol Deace and prior to writing this post, I finished the NES version of Fantasy World Dizzy (Mystery World Dizzy), a version of that game I'd never actually played prior to this; and it isn't bad at all.
If anything, I prefer it to considerably more capable emulation-based handhelds I own that are capable of playing much more graphically intensive games and, to put it bluntly, games I'm more familiar with. I only have a passing knowledge of microcomputer stuff, and yet here I am, eyeing up a Team 17 Amiga collection and thinking "wouldn't it be super fucking cool to play the original Alien Breed rather than the PS Vita remake?". Similarly, there are various carts of modern homebrew titles made specifically for older consoles, like the recently released Goodboy Galaxy cartridge, which may very well be the only general retail release of that title that isn't a highly FOMO-based limited production run; and while you can buy the ROM direct from the developer and just emulate that anywhere, I'm eyeing up this cartridge just so I can say I own it. Honestly, the homebrew stuff is the real draw for me here, since a lot of these titles just won't get any physical release otherwise, and yet, it'd be really nice to own them and have them playable on a device that's made by people who seem to "get" what I personally want out of a portable console.
