Suicide battery
Please refer to the FD1094 and FD1089 suicide battery page for more information on this issue.
XRGB-2 Specific Settings
Video is up scanned without problems, however the resulting vertical and horizontal frequencies are not standard TV ones and it might not work on some TVs that can't sync with such signals.
The frequency generated by the XRGB-2 when using this PCB is 57.4Hz and it has been verified as working on CRT monitors.
XRGB-3 Specific Settings
All this information applies to the GAME IN port only, using RGB21. Works without problems in B0 mode, however due to the uncommon sync frequency used by System 18 games, the XRGB-3 generates the appropriate up scanned signal at 57.4Hz which might be incompatible with some displays since the standard TV frequency is 59.94Hz. It has been verified as working on a CRT monitor.
