Yup, try that but with no luck, received error "invalid data source", but my GeoMedia file can be opened with ArcGIS with FME plug-in directly.

comment Predefined CRS and Custom CRS problem with Borneo projection
i try using spatial reference tool to generate the Proj4 format for Timbalai 1948/ RSO Borneo (m) +proj=omerc +lat_0=4 +lonc=115 +alpha=53.31582047222222 +k=0.99984 +x_0=590476.87 +y_0=442857.65 +ellps=evrstSS +units=m +no_defs and assigned the shapefile to this new custom CRS. the output still cannot match the two CRS together. the new user defined CRS using spatial reference tool still go to North 300,+++Km

@AndreJoost Yes, the newly saved shapefile displaced as well. but if re-assigned to EPSG:29873, it will be back to the desired place. so i assumed i did not create the user defined CRS correctly.
