which dreamcast model will play burned games
Like I said above, the latest hardware revision of the Dreamcast still had Mil-CD code, but the playback of Mil-CD is disabled (much like the Ps3, which still has the ps2_emu, but disabled), this revision was v2 (there were three DC revisions: v0, v1 and v2) and you require a modchip to play burned games.
