Hyperkin's reveal of the "RetroN 4
" console at the Midwest Gaming Classic turned out to be the unveiling of the RetroN 5, with the addition of another
cartridge slot for Japanese Famicom games (which have 60 pin connectors vs. the NES's 72 pin). Now the console supports Nintendo, Famicom, SNES, Genesis (plus Mega Drive), and Game Boy Advance (with Game Boy/Color support), all over HDMI, with controller ports for NES, SNES, and Genesis controllers, as well as its own wireless Bluetooth controllers. The company plans to make the controllers remappable and usable cross-platform, but those features are still in the works.
The console upscales old games to HDMI with special image processing to make them look decent on HD screens. It also supports save states just like emulators do, with an SD card slot to store saves. Furthermore, you can speed up gameplay and remap the Bluetooth controller buttons to control these features.
Hyperkin doesn't have a firm price or release date, but is hoping to release the console around July for less than $100.
