Lately I've decided to get more involved in the speedrunning community (probably by running DK64 and Banjo-Kazooie), but my problem right now is that my PAL N64 games run much slower than NTSC. That means I'll have to buy some American cartridges and possibly a TV that supports NTSC. I recently got an American N64 with a power supply from ebay and I have this transformer to run it in Europe:

So here's my problem: Converting from 230V to 120V works fine with this equipment. But the output frequency is 50Hz while the American power supply seems to require 60Hz, so I'm not sure if games can run properly with it. I haven't gotten any games for that console yet, but I ordered DK64 and I'm waiting for it to arrive. So in the meantime I'd like to know if the N64 could run properly without getting damaged by the transformer or if I should get some power adapter. I'm not experienced at playing games from different regions, so any help is appreciated.
