The error is self-explanatory: you're using 32-bit read/write handlers for an 8-bit CPU. That doesn't happen in any version of the driver distributed by MAMEdev, so you must have screwed something up badly.
Note that we generally don't support backporting drivers; it's effectively impossible to go from current MAME to anything pre-0.106 without just writing a new driver from scratch for the old core, and mobile devices are finally coming with CPUs that handle modern MAME with no modifications (e.g. the Nvidia Shield).
