Nintendo are becoming King of the Cock-ups, taking over from Sony. The Wii U is becoming a bit of a circus clown. But I remember when the Nintendo 64 was released, Nintendo had the bright idea of charging £54.99 for Wave Race 64 which had terrible black borders, but I can't recall any slow down. On top of that, there was no battery inside the cart to save your progress, so you had to buy a memory pack, which set you back £19.99 I think. In Japan, they re-released it (Wave Race 64 Rumble), so that it was rumble pack compatible, but because there was only one slot in the controller, you couldn't use a rumble pack and a memory pack at the same time. I'm not sure if Wave Race 64 Rumble had a battery inside the cart. Nintendo canned a rumble pack with built in memory, but I think you could get third party ones. I remember many SNES and Nintendo 64 games having borders and that wasn't just Nintendo games. Nintendo have always s**t on European gamers, more so since their European HQ moved to Germany. But all in all, you can't beat having a game on cart or disc, more so if it's the US version (having US consoles) which offer full screen games. It was the same case with the SEGA Dreamcast. The European version of SEGA Rally 2 wasn't full screen, the slow down was just annoying, so it was yet another p**s poor decision by SEGA Europe. In the end, I bought the US version which was full screen, the Japanese version had an exclusive Ford Escort rally car (yes, a big wow at the time....).
