This (pirate) version of Frogger was a conversion on a Scramble board set.

2K files are 2716
32 byte file was read as an 82S123 (the colour PROM)

Two ROM sockets on the video board were unpopulated. There were no changes made
to the video board, but the sound board has the following modifications:-

Lift pin  2 IC K4 (LS28)
Connect pin  2 IC K4 (LS28) to pin 13 IC E4 (LS42)

Lift pin 13 IC J4 (LS04)
Connect pin 13 IC J4 (LS04) to pin 11 IC H3 (LS08)

Lift pin  8 IC H3 (LS08)
Connect PAD  8 IC H3 (LS08) to pin  6 IC H3 (LS08)

Lift pin  5 IC J5 (LS04)
Connect pin  5 IC J5 (LS04) to pin  3 IC F5 (LS08)

Lift pin  3 IC A1 (LS04)
Connect pin  3 IC A1 (LS04) to pin 11 IC F5 (LS08)

Lift pin  9 IC C5 (2716)
Lift pin 10 IC C5 (2716)
Connect pin  9 IC C5 (2716) to pin 14 IC G5 (LS245)
Connect pin 10 IC C5 (2716) to pin 16 IC G5 (LS245)

Connect pin  8 IC 3D (AY-3-8910) to pin 10 IC 3D (AY-3-8910)

The 220R resistor connected to pin 1 of IC 1E (8255) has it's other leg
strapped to ground.

This conversion has been verified.
