I wanted to play Metroid again, and having a handheld capable of playing all classic games in one, I wanted to give it a go!
Metroid 1 was done with Zero Mission. I played and beat NES Metroid and can confidently say it’s not my cup of tea. Love Zero Mission and love replaying it.
Metroid 2 was done with AM2R. This was my first time playing and beating AM2R, and a handheld is the right way to play it. Might try to beat the original and the 3DS remake… eventually but it’s not my favorited Metroid.
Super Metroid. I have the snes game, I played it here and… it’s a love hate relationship. I played and beat it before, but not in a long time. And coming off of 2 fusion clones, the controls are way too floaty and watered down for my poor muscle memory. I also got lost… a lot. And it took my 4 hours of game time. About 2 weeks of on and off play time. Ultimately I like it, but this is the oldest I can recommend anyone going back in Metroid.
Metroid Fusion. My personal fav since it was my first game (the save battery died in my original game as a kid and I can beat this game on 2 AA before they die). Snappy fast smooth and I just love this game and replaying again for the untenth time.


Try to play them in real hardware or FPGA with SNAC and a CRT. Old games are a lot more difficult today because we are adding lag (input and/or screen). I remember to play Super Metroid in emulation and the jump to wall thing was so hard because the lag. I love 2D Metroids, the 2D one in Switch is cool too.
Most of these were GBA, which I have and honestly the emulation of mGBA is spot on. SNES9x didn’t feel off from an SNES either. At least not enough to make chaining the space jump easier.
I heard from one of the reviewers that the Pocket Nova’s input lag is the same as the consoles because of the custom horizontal screen
According to this vídeo https://youtu.be/usQQ42egzus the nova has 12 frames of latency with run ahead enabled. For me thats too much lag for some retro games, like plataformers or shmups for instance.
