Bomberman 1 and Bomberman 2 both work fine in openMSX. Tested with Boosted MSX2 EN and turboR configuration.
If you get Illegal function call in 2 (which I got on a turboR), the issue is a bug in the game. It doesn't handle the fact that Japanese MSX machines start up in screen 1, and simply does a WIDTH 80 without changing to screen 0.
If you do a screen 0 and then RUN, it works fine 
You can also let the MSX boot in screen 0 by doing set screen after doing a screen 0 or simply fix the autoexec.bas of the game.
a bug, a bug.... more like missing feature.. lol. We didnt have the possibility to test these games on all sorts of MSX machines, they were developed on (i believe) NMS 8245, 8280 and Sony F700D. 
Good to hear the games are working fine.
