Update: here is a fancy astdlx adapter I built a few of which contains a vector flip circuit, an attempt at equalizing out the audio, some configuration jumpers, LED etc. I did this originally for myself and just for fun, but if there is enough interest I could run a production run of these until the counterfeiters steal and copy it like they always do.
The original poor mans design is below

Step 1 Materials needed. 44 pin edge connector 56 pin jamma finger |
Step 2 Cut 56 pin jamma finger down to 44 pins. |
Step 3 With a Marker place an "X" on pins 12(N), 13(P), and 15(S) a little bit off center from the middle of the finger. Label the edge connector for parts side. |
Step 4 Drill 1/8" holes through the finger at the places marked in step 3. 1/8" is wider than the finger trace, goal is to break the trace and provide a hole to thread the wires through. |
Step 5 Solder 44 pin finger to the edge connector. Make sure you match up the parts side. |
Step 6 Cut and solder 6 short wires to the edge connector tabs for the 6 traces cut by the holes. Feed the wires through the corresponding hole. |
Step 7 Another pic of Step 6. Wires should be around 1" long. |
Step 8 Cut the wires as to minimize any excess. Solder the other end of the 6 wires to the opposite side of the finger board. |
Step 9 Close up of final adapter. Congrats! |
