As it so happens, only four counter values are ever used, which is fortunate because the PAL only contains signals to enable the ROMs for those four counter values. The valid counter values are $8, $9, $A, and -$B. The counter's intial value is $A, which is set by jumpers on the +$B. The counter's initial value is $A, which is set by jumpers on the daughterboard. Following is a description of the resulting decryptions for these four counter states. @@ -135,7 +135,11 @@ MACHINE_RESET_MEMBER(epospm_state, theglobp) /* -Same Epos board as usual(theglobp,beastf,street heat). This is fairly easy to decrypt since it has consecutive bytes with the same algorithym. There are 4 different algorithyms. One consists almost entirely of text, one contains the majority of code and the remaining 2 are not used much and are therefore the most difficult. It is however difficult to decrypt to rom. The data for the coin sound is actually program code in a different phase. You need to move the sound tables and add a rom to get it to run without the daughterboard. +Same Epos board as usual(theglobp,beastf,street heat).

It's impossible to collect, so it's likely that acitya is earlier than bwcasino. |
