What OS ? Never had problem with Frogger on Pistorm on my side. As alternative you can use Riva. See player.ini file.

3.2.2 froggerNG plays but crashes at the end
ive enabled riva to get me going but no videos now odd as i have riva as the default mpg player and i can play the mpg files by double-clicking them,
initially, the game would crash after 30 seconds on a map using Paula fast 8 bit stereo++ on unit 0 changing this to DMA 8 bit stereo allowed me to play i had a good 2h skirmish
both on pistorm classic with pi4 and pistorm32 pi3
