Those two games are provided as multi-segment BIN files.  The first
segment loads a jump table into low RAM.  That is followed by a large
number of 255 byte segments with the code and data starting at $1C00.

A quick look through the code reveals some absolute JMPs to the $2xxx
range, so my guess is they probably won't run from the Cartridge ROM
address space.

One possibility would be to create a small loader routine in the ROM
followed by the BIN file data so that the game is loaded from ROM into
RAM at startup.
