TUDE was good too / T.U.D.E.
You have to remember that most games were programmed before the 68020 / 68030 were widely adopted, so game programmers targeted their mass audiance - 68000 KS1.2/1.3 Amiga with 512K / 1MB Chip RAM. Now this wouldn't be an issue if they had followed Commodore's programming guidelines but most didn't care about such things, so we hit a few problems with some games. TUDE or Degrader are great for running old floppy games (especially coupled with softkicking Kickstart 1.3). Fast RAM can be disabled too, as well as all CPU caches - coupled with Kickstart 1.3 you should be okay. Lots of other options too I can't remember...long time ago since I fiddled with such things. So yeah, with a degrading tool (and possibly just softkicking 1.3) you should be able to run the majority with your GOTEK (that's my educated guess).
Ultimately, best solution is WHDLoad in my opinion, as it saves all of this hassle with old games. I have 2000 games in a menu, all installed on my hard drive. For GOTEK though I'd use an A500 or unexpanded A2000 for floppy game compatibility if it was me.
