Do they do this every year? I don't have all my retro equipment set up at the moment and I've got other priorities this year...but I'd be excited to get them eventually!
Everdrives are the top of the line flashcarts for various retro systems. They allow you to boot roms and romhacks on original hardware without any modification required. For each system, there are various price levels that give extra features. For example, the GB X7 provides a rtc (aka Pokemon games keep time) but is more expensive. The only sale they typically do during the year is Black Friday event.
An Everdrive is a flash cartridge that allows you to play games on your console. The cartridge is easy to use. You “drag and drop” files from your computer onto a * micro SD card that you insert into the Everdrive. When you turn on your console, a list of games will appear. With your controller, you select the title, and you're done!
Do any of the GBA carts work with the Gen 4 Pokemon PAL Park feature? Or is there a different flashcart that works aside from Reproductions / Original Game Cartridges?
It will not work with PAL park. I believe the EZ-FLASH OMEGA Definitive Edition can use its "Mode B" but the build quality isn't great with those and there are a lot of reports of people losing saves.
The other option would be something insidegagets flash cart but that also needs their flasher.
Dang, that's a real pretty penny for the InsideGadgets route!
Still, that's good to know that a decent DIY option exists for those that want to play the GBA Pokemon games without gambling with Reproductions or paying out retro scalpers.
