Are you OAGD.net user? If you create account and log in using FS-UAE launcher, you only need to scan your Amiga roms, floppies, whdload games etc. FS-UAE Launcher creates automatically correct and working configurations for all games which are in OAGD.net.
Transplant seems to be on there and seems to work without issues.
Edit. If you want to do it manually, here is settings Launcher shows for me:
Amiga model: Amiga 500, Accurate emulation
Kickstart: Default (KS 1.3)
Chip mem: Default (512KB)
Slow mem: Default (512 KB)
Fast mem: Default (0 KB)
When you set those settings on laucher, emulation uses automatically correct chipset for Amiga 500.
If you want to run it from hard disk, I would recommend whdload version.
Second edit:
If you want to manually change chipset, there is Custom option uae_chipset. Take a look at
