Well, there you have it folks! After the NesterDC 3.0 source code being available for a while now, someone expanded it, adding many new mappers, and many other changes. The homepage can be located HERE. Here is a snip of the changes from the homepage:

Changes to expand NesterDC

* apu engine was ported from
unofficial nester (http://www.emulation9.com/takeda/).
* mappers were ported from
unofficial nester (http://www.emulation9.com/takeda/).
0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 13, 15, 16, 17, 18, 19,
20%, 21, 22, 23, 24, 25, 26, 32, 33, 34, 40, 41, 42, 43, 44,
45, 46, 47, 48, 49, 50, 51, 52, 57, 58, 60*, 64, 65, 66, 67,

235, 236, 240, 242, 243, 245*, 246, 248, 255
(*: partial)
(%: don’t work on NesterDC)
* set gcc optimize flag for SH4.
* change default frame skip to ‘1 per 3 frames’.
(I feel ‘1 per 2 frame’ works 100% speed, but this cause
vanishing sprites on pseudo transparency).
* delete timer_sleep while loading ROM indexes.
(it’s bottleneck when over a thousand ROMS)
* some misc changes…

You can pick it up on the NesterDC Page.
