I've made a set of small patches to Thunder Dragon 2. The following features are added:

* P1 Autofire on button 1 (no need to add interstitial JAMMA adapters)
* P1 button 3 mapped as non-auto button 1
* P2 is able to start a game without P1 joining (even with multiple credits inserted / free play)

The IPS patch and sources are available from https://github.com/Mikejmoffitt/td2-enhancements .

This sounds really convenient. Thanks for making this available!

I'm testing out these patches and while the autofire is really nice to have, I'm not able to start a game with free play enabled on 2P ship only. If I press 2P start, it begins with 1P and 2P. Do the dip switches have to be set up somehow special to enable this feature? I have SWB 1-4 on for free play, SWA-7 on for no demo sounds and the rest off.

Also, I noticed that originally you had stated that DIP1.4 is unused, but according to this page, it shows as used for difficulty select: https://www.crazykong.com/dips/ThunderDragon2.txt . I've been using that page for reference, is it correct? Thanks!
 
The Free Play is a bit of a silly episode. I didn't realize that TD2 actually offered its own Free Play mode, so I hacked in one completely of my own. Then, a friend pointed this out, so I removed mine.

If you have the old build with my own Free Play, then it's DIP 1.5 - that was my mistake in noting which one is used. In that case, you should leave SWB1-4 to a coin setting, and set SWA 1.5. Then, you will have my Free Play, which lets 2P join without 1P.

The old version with my Free Play is available here: https://github.com/Mikejmoffitt/td2...6ed9147584712609/td2-enhancement.ips?raw=true

(it is also 666 bytes, which rules)
