Ooh, I use .cdl hex codes: If bit7 is set, that marks the start of a function. If bit0 is set, that makes the code active (or makes it appear like it has already been run). A hex code of #$02 specifies that the byte is part of a data section. A hex code of #$00 specifies that the byte is part of unk...

This can be done with the "Mark selection as..." option in the right click menu either in the memory tools or the debugger's disassembly view, though the latter has the shortcoming that it can't be done on a byte-by-byte granularity. tokumaru, to speed up the “Mark selection as...” process, and to ...

^What would you check if the MMC1 PRG banks suddenly become bank #0 and bank #1, after the first, of 5, bank-switching writes to ROM?

PRAISE GOD!! :D :mrgreen: Wow! Can log in again! Thank you so much tepples, and, on IRC, Kufat, jero32, and genuisAZK (I think that’s how it’s spelled)! :D —- Our game uses MMC1; it’s set to use 32 PRGROM banks, 8kb of PRGRAM, and 8kb of CHRRAM. PRGROM Banks #15 and #31 are the only banks that can b...

Hi, no one has mentioned Famitone 2... why? That’s what I’ve been using... it’s excellent to convert Famitracker to nes use.

It’s written extremely great by Shiru. Have learned some nifty 6502 tricks from time spent watching/looking-at famitone’s code.

Sorry, it took some time b4 learning how to do ^this... on page 13 there’s an example in the middle of my post when I quoted tepples:

edit: If it’s too much work, don’t worry about “fixing” that it is just uncomfortable.

Hi... just wanted to point out that since the quote code has been “-mark-lessed, all of the effort that was used to color the non-username parts of (or add urls to) the quote title has been turned into hard to understand massive amounts of text. Maybe, could someone add a date consideration to the b...

This post tries to elaborate on these responses. :) Individual background tiles can not be moved around like sprites (otherwise they would be called sprites not background tiles) so there are no overlapping of background tiles, or is it just too annoying to keep it from overlapping a tile with a dif...

Only the best emulators include a "blow on the cart" option.

Have never stumbled across that best emulator option in Mesen... Sour, this is disappointing

If you have a hidden name table, and a hidden pattern table, the order of the updates doesn't matter at all. You just have to make sure that all VRAM updates take place during vblank or when rendering is turned off. Ahha! Yes! Thank you for helping clear my muddied thinking. :) Half of my brain was...

Hmm... so the proper way to change CHR tiles is to first draw the entire new screen with the wrong CHR tiles, and then write the new CHR tiles, then switch to the new screen’s nametable and finally adjust $2000 to display the background with the new CHR tiles? Whether you're gonna update the name t...

I’m unable to remove/edit that line bc Mesen always gives a long message that starts with, “An unexpected error has occurred.” Thanks, this should be fixed in the latest dev build now. You’re welcome. :) Thank you so much Sour; using 0.9.9.13 now, it’s much smaller than 0.9.9.0 :D; am now able to f...

Sour, or anyone else, how can I remove a mistyped Watch entry? I typed [9C,2] , but I’m unable to remove/edit that line bc Mesen always gives a long message that starts with, “An unexpected error has occurred.” So, now there’s an immovable line with a red “<invalid label>”; all it needs is a ‘$’; th...

Thank you tokumaru! :D (Going to try your #2 option/suggestion.) Yeah, I'd probably go with that too. And make it slightly more flexible even, by always writing an RTS after the last transfer, and remembering that position in order to restore the LDA once the transfer is done. That way the routine ...
