You can simply hack the rom to remove the region lock.
Go to romhacking.net and download GGGuy. Then, open your rom with GGGuy and patch the corresponding Game Genie code into the rom (the code for Worms is in this document: https://gamefaqs.gamespot.com/genesis/9 ... faqs/60595
). Next, you need to fix the checksum of the rom (this can be done with the tool Fix CheckSum from romhacking.net, but you need to change the file extension to *.bin, otherwise the tool won't let you select the rom).
In most cases there is no need to play any PAL ports as they are usually inferior because of their lower framerate. There are only a few exclusives for the PAL territory. Most of these can be patched in the manner described above (for the more popular games like Mega Man or Zero Wing there are even dedicated PAL to NTSC patches available at romhacking.net).
