Here's FCEUXD SP 1.03 which adds some new features and fixes some others. Special thanks goes to TFG who significantly improved and sped up this release with his feedback (which you can see in the FCEUXD SP 1.02 thread).

Here are the changes which are while few quite significant I think:

- New: Added register P (Program Counter) to the conditional breakpoint expressions.
- New: There's a new name list file for symbolic debugging. Put all debugging information
for addresses < $8000 into the name list file romname.nes.ram.nl.
- New: Added a feature to NL files to support arrays.
- Bugfix: Names for offsets can now be properly distinguished from byte values. All
offsets have the four-byte format $XXXX now (including zero-page offsets)
while all byte values have the two-byte format ($XX). This fixes some bugs
and issues with NL files.

Enjoy! Just like every release of mine this one's barely tested. I hope you don't find too many bugs. And if you do, report them please.

Awesome again! I just stopped by to see if anything new was up, and amazingly enough, a new release. I even figured out how to use the symbolic debugging. Keep the changes coming, I'll take a look at it and tell you anything that might make it easier.

By the way, I noticed the other day that the hot key for changing a FDS disk side is also F6. FDS games use the F6 and F8 keys. I didn't know if you were aware of that, since F6 is the hot key for opening the hex editor.

Thanks for reporting the F6 issue. I was not aware of that.

Only missing 1 thing that would be very helpfull to me: 7Zip Support!!!

I see you can play games for .zip and .gz archives, yet not from .7z. This isn't that big a deal, I just have to manually convert all my .7z files to .zip.

Anyway, great job so far!

Greetings sp,

I just had time to test the new FCEUXD SP 1.03. I found a bug when using the array feature. I couldn't determine a consistent pattern so I'll post the scenario that worked most of the times.

BEGIN OF .NL FILE
$F55B/26#dat_Level1#Start of level 1 data block
\ [$F55B-$F57D] Pallete data
\ [$F57E-$F58B] Attribute table data
\ [$F58C-$F71B] Pattern table data
END OF .NL FILE

The array feature works all the time as long as you don't jump (Seek To, in the debugger's window) to the CPU address that is marked as the array's beginning.

As for the size, it varies. I tried larger sizes, none worked. I tried removing the multi-line comments and it didn't work.

// Actual output
$F22D:B1 00 LDA ($00),Y @ dat_Level1[0] = #$3F

If I press 'Seek To' ($F55B, array's origin address) FCEUXDSP crashes.

If you are unable to reproduce the bug and want the actual files, drop me a line and I'll mail them to you.

TFG.

Thanks for the bug report, TFG. I'll look into it. Probably not today or tomorrow but later this week.
