I got an Rg35xxx about a month ago and it has been fantastic!! I didn’t replace the stock OS as a lot of folks suggested because the stock one already has everything that I need it to do. If I had one complaint, it would be that the battery isn’t great. I haven’t had it die on me while out and about yet, but it can cut it close. Overall, I highly recommend it for someone into retrogaming old gameboy advanced -ish era games.
