Thanks, it's a MAME bug rather than the cheat engine though....it seems it no longer handles leading zeroes properly in condition fields. Odd.

Use the lua plugin cheat engine (Plugins>Cheat from the MAME menu)...it works fine in that.


Alternatively change all three:-
maincpu.pb@124035==04 OR maincpu.pb@124035==0B
to
maincpu.pb@124035==4 OR maincpu.pb@124035==B

Like I say odd.......

Feature not a bug, immediate numbers with a leading zero are interpreted as octal now. The plugin doesn't replicate that (and hopefully won't have to).

Luckily the leading zero is not taken as octal, it needs to be 0o.

The problem here was 0B, which since a few releases ago is the prefix for binary everywhere

so
maincpu.mb@0b00=0b would become maincpu.mb@0000=0
but
maincpu.mb@0b02=0b would still become maincpu.mb@0b02=0
as there is a little bit of handling in the expression file to check for invalid binary values and to revert to hex if it hits any....though I'd argue that a sole "0B" is not a prefix if it's got no numbers after it.

So yes, it's a feature rather than a bug. Though it's a annoying feature nonetheless

I had to update my cheat.dat converter so now any 0b?????? are converted to " b??????"...(? = 0/1)
this will be reflected in the next cheat release here and on wayder's site.

on raiden 1 game on all versions the infinite bombs doesnt work
you can just throw 2 or 3 bombs but after a little while no bombs are throwing down even if you can see you have infinite bombs
