Ps.: I have a Airton Senna (Nigel Mansel Hack) too.
If somebody wanna dump I can donate (I just have to find the cartridge)...
If it hasn't been dumped yet, then I'm sure you'll be able to find someone willing to dump it. The more the merrier!
I discovered that it's already dumped...
It can be found in various websites that distribute this kind of media... :p
Unfortunatelly, I can't say the status of the dump, but seen to run well in most emulators
