Damn, got 4 great 7800 games, but they are PAL

1st of all I apologize as this topic has been mentioned several times. I have found various answers to this topic, but they left me confused. I live in a NTSC region and my 7800 is NTSC of course. I bought 4 PAL mint CIB games, they are :

1-HES TitleMatch Pro Wrestling
2-HES Super Skateboardin'
3-Alien brigade
4-Super Huey UH-IX

I was told the games will just flicker in an NTSC region and console, but they don't work at ALL, just the Atari splash screen comes up, then a black screen for all 4 games. So my question is :

Will just getting a PAL 7800 console make the games playable, playable as in %100 normal, no color issues, sprite, etc ? Or will I need a PAL TV, PAL POWER SUPPLY, NTSC TO PAL converter, etc? Or am I simply out of luck?

I hope I don't have to sell off these games. I've trying to find Alien Brigade like forever, just to find it unplayable in my NTSC console

Come to think of it, I'd be happy to just get the games to be playable, I can live with color differences, or whatever else. I hope I can get a definite answer and put my agony to rest!! Any advice would be much appreciated !!!!! Thank you in advance!!!
