These seem to be the truth values. MAD1 && MAD1A are functionally equivalent. MAD-1/MAD-1A OUT0 = ((!A0 && !A2 && !/ROM && !MODE && /RESET) || /ROM || (A2 && !/ROM && MODE && /RESET) || !/RESET) && (Vbat < Vcc) OUT1 = ((!A0 &...

Any further progress on this?

I could also spare some space/traffic on my hosting as well.

Above link fixed.

As usual, Had to rip an SPC and try to figure out what commands drive it. Command goes on Port 1, and issuing that command, goes onto port 0. If a command is valid, what is written to port 0, is echoed back, otherwise it is not echoed back. Regardless of whether the value is echoed back, next comman...

Awesome work on vgm2spc. I have a bug report for the current version. if ((outData.size() + extraDataBlock.size()) > 0xEEC0) { printf("Error: the vgm data is too large to fit. the maximum size after packing is 61120 bytes\n"); delete [] vgmData; outData.clear(); return; } That should actua...

Best practice, is to use $0000-01FF as ram, end the code section with a loop of some sort, even if it is a jump to self type infinite loop. In regards to the sample directory, you indicated a looping sample, yet you didn't define the loop address within the sample directory. In other words, here is ...

romhacking.net does NOT allow hotlinking to any of its documents. Even copy/pasting the link does NOT work. You instead have to link here.

OK, I've updated the archive with a lock implementation. Awesome work. However, in your lock source code, you may wish to make a correction. Currently, it says. ; --------------------------------------------------------------------- ; ; pin configuration: (cartridge slot pin) [original 18-pin SMD l...

From what I can tell, the key is NOT able to tell which lock region it is running on. On the other hand, the lock IS able to tell which CIC key region is currently being used, if programmed right. When the Lock/Key have initialized their seeds, the Lock sends the lower bits of ALL of its side to the...

Darn. I tried scanning a Super Mario World and a Chrono Trigger SPC, using a program that tried every byte value on each of the four ports, checking to see if any caused the SPC to re-run the IPL ROM. None did. So it seems that each SPC driver will need to be manually examined to determine what, if...

mic_: You may wish to include Terranigma in your test set. You will see why skipping the writing of FFC0-FFFF, and forcing register F1 to 8x is a bad idea. Oh, and FF70 in that games SPC driver is USED. better implement a free space search algo, then use FF70 as a LAST resort. Write 00 to both KON a...

--- EDIT: You wrote: "that third ROM is 768 bytes, which I don’t handle in my little conversion script, so you’ll need to remove the extra columns (they are empty anyway)" Actually, there is one byte in there that is not empty. I wonder if this corresponds with your 'mystery' opcode in so...

Didn't mean to jump the gun there. Sorry about that.
