What is on the cart-PCB, can be seen in theschematic (pdf)
and theplaceplan (pdf)
. It is the same design, Timmy Brolin used (adress/data-demultiplexing with 74AC191 counters for random and sequential access), except that my cart uses a 128MBit Intel Strata Flash (TE28F128J3C120) and low-voltage single-gate-logic.
If you manage to get theboard data (Eagle V4.13 format) on a 1mm (originally 0.8mm) thick PCB, the board fits perfectly in a original cart housing. Mine has a thickness of 1.5mm, so i have to do a bit extra work to get a suitable cart-housing.
As you can see in fig. 2, i used an old folded business card to do the first initiation of the prototype card, to fit properly into the cart-connector of the GBA.
