@alfa75 I would like to give a shout out to Ulrich all the way in Switzerland and his store https://retrogame.ch/.
He made it fast and easy for me to obtain the game.
27C800 chip with Metal Slug 2 Turbo to replace the original 241-P1 ROM
UniBios 3.3
Do to language barrier the first package missed the UniBios. I don’t blame him for this! It was bad communication on both sides We solved it and he was really kind and send me the bios with out charging an other package or anything.
Everything he send me was in perfect shape and worked really well! I’m totally happy and I’ll order from him again if I need something! He is totally trustworthy, thank you very much my friend
He made purchasing the game (Atari Tetris) easy, provided good pictures, and shipped the game when he said he would. It's a small game, and was well packaged, shipping was quick, and the total price was very fair.
