I am not the person you are replying to, but I am curious as to why you say avoid everything EZ-Flash just because of their support service?ds is a mess, there's like 50 different kinds and it's impossible to track what's where and what the best places to get them from is
acekard 2i is technically the best, r4i gold 3ds plus (r4ids.cn branded) comes in second. good luck finding acekard these days though. r4i gold 3ds plus is more recent so maybe it's still in production at least?
stay away from anything ezflash, garbage tier support I dont think I have to elaborate on that. if you're going to spend $60 on a gba card you might as well do the extra $40 and get everdrive gba for $100 and have an actually good card. goomba/goomba color is pretty good and majority of games run full speed with minimal graphical problems, so you might be happy with just everdrive gba, play gb/c games in gba mode with the emulator. everdrive gb is more expensive if you absolutely want to play games in gbc mode or on gbc.
I personally have had an amazing experience so far with my EZ-Flash Omega Definitive Edition. The singular issue I have come across with it is that I cannot patch ROM hacks with the save-state mod. Otherwise, amazing hardware imo.
I have only had some issues with the EZ-Flash Parallel, hence the creation of the original post, hoping that @EZ-Flash2 would fix the issues. And they progressively have been, but it seems as of recent that it stopped at v1.06.
