If you're someone who backed the indie developed Megadrive/Genesis beat-em-up Paprium and never received your copy of the game, you may be interested to find out it's now finally been fully emulated via Retroarch, using a special genesis_plus_gx_libretro core. Watermelon Development, who produced it, was seemingly only capable of actually making a handful of copies, leaving loads of unhappy customers still waiting on a game they paid for almost a decade ago.
Many people have labelled this one of the biggest retro gaming scams ever, with over a million dollars taken and precious little to show for it. Paprium has apparently proven difficult to emulate up until now due to its alleged "custom hardware".
I won't paste any links to it, but it's not difficult to find. The one I found came with the custom Retroarch core. I just had to go to the Retroarch cores folder and replace the Genesis_plus_gx_libretro.dll with the new one. After that just load Genesis Plus GX Core then find and load the game .bin.
When you first load the game up you play a fake low res "mockup". To get past the mockup, the very first time you play, you need to let the enemy players beat you in that part, so your character properly dies. If you restart after that, you should be good and the full game should load.
