paul eeepc 4b0c340eb1 Creations of operation module and dictionary.
Things appear to be working with some early testing.  Assumption that oper_info elements
are aligned in SRAM linearly appears to hold true.  Researching this I found it probably
was true, but can't be certain esp if gets changed in the future to not be purely 8byte
sized elements.
Still need to provide means to decode function numbers info function pointers.

Paul Molloy 876b526e8c Some timing tests on windows machine. Double buffering was pretty
successful only 1KBps speed drop when actually dumping real cart data.

paul eeepc a7eaf970b2 CHR-ROM dumping working for NROM checksum appears to be off need to compare files. 2016-12-12 10:56:53 -06:00
paul eeepc c2359e67a5 Dumps offically working for PRG-ROM on NROM!!!
Found bug with setting map_n_part due to >/< instead of >=/<= for setting called_buff...
Was also setting mem_type and part backwards in dump.c
The had issues with usb timing out for more than 1 buffer read back
Problem was due to lack of usbPoll while dumping during double buffering
Adding usbPoll to page read to correct issue

Appears to be issue with dumping first byte of this choplifter cart I'm testing with.
Not so certain it's my bug though..  No matter what I do the first byte reads
back 0x78 and copy I downloaded has 0x00.  Setting my first byte to 0x00 also
creates proper CRC32 according to bootgod's database.  So need to look into this more
to figure out what's going on.

paul eeepc 49ec51e767 Much of dumping code for PRG-ROM completed but have some bugs with setting buff elements working on debugging... 2016-12-11 20:34:43 -06:00
paul eeepc 4db2929c3b Big overdue commit of past few days effort..
Detecting mirroring code working and tested
Started working on buffer operations from host
Current code compiles but not yet at point where can start testing
Adding cpu page read to nes.c to have faster dumping operations.
moving enums to shared as gets used quite a bit communicating between device and host.
