For greater compatibility, I recommend trying out this new version of the Minekart Madness ROM:
https://github.com/mhughson/mbh-cart/releases
This MMC1 version of the ROM is essentially identical to the version originally uploaded (minkart_madness.nes), but uses a much more common Mapper (MMC1), which will work on almost any device.
The gameplay and features between the 2 version are identicle.
