[frogger] philmurr fixes

[fedekrum]

There is an excellent work done by philmurr at https://forums.arcade-museum.com/threads/frogger-bugs-descriptions-and-fixes.482765
to fix known Frogger issues (for example a valid move to a log resulting in a frog's death)
Based on that work I made a cheat file with all his fixes for the latest MAME.

It has been ported today to FBNeo and it is on its cheat library now.
I don't know how to port it to older versions of MAME

Here is the XML file.

Here is a video of it in action.

Thanks, reduced number of cheat lines (.w & .d used & dropped the pointless text from 2ff5-2fff) and added. Just added it to frogger at the moment...will probably work for most of the clones "as is".

... reduced number of cheat lines (.w & .d ) ...

Thanks for adding this fix @Pugsy.
Where can I learn about .w & .d ?
Not sure what that does.

thanks

.b means byte (8 bits)
.w means word [2 bytes, 16 bits]
.d means doubleword [4 bytes, 32 bits]
.q means quadword [8 bytes, 64 bits]
