Preview after submitting posts?

When submitting posts, I am now getting sent to the preview screen, which is prompting me to edit or submit the post. That happened twice today.
Despite of the preview, the post was submitted (if I submit it again, I end up with a double post, and have to delete the second post).

Re: Weird famiclone with infrared controllers

Before randomly buying new components, another step back: use fresh batteries (if you didn't already try that).
I would recommend the "Use-a-LED-instead-of-a--Multimeter" trick only if you are really completely unable to figure out how to use your multimeter.

Re: Rem Demo

Looking into a Vram Viewer, there seems to be a 2-dimensional array of 16x10 tiles (representing a quarter-circle) for the shadow mask. But each tile is having only a single brightness (instead having tiles that fade from upper-left bright to lower-right dark). So you could as well use a 1-dimension...

Re: Strategies for implementing macro functionality in assemblers

I would process macros is two passes, first replacing the parameter names by the actual parameters, and then assembling the resulting source code as usually. That steps can be implemenented line by line, so there aren't huge amounts of memory required during macro processing. However, it would be be...

Re: listen to a 6502 emulate a 6502 emulating a 6502

Not bad. A possible workaround for the problem might be a Playchoice10-style fix: Emulating an additional Z80 processor, then the emulated Z80 could simply reset the emulated 6502 when sensing the execution of BRK opcodes on the crashed 6502 (you may need expansion RAM for the Z80 memory).

Re: I accidentally discovered what Double Dribble was probably intended to sound like.

That stuff happens all the time, even in professional music, https://m.youtube.com/watch?v=n55cl7MOmsg you'd never know if the last 20 seconds were actually intended to sound like that.

Re: Max stack depth + OAM transfer

Do you really need the uncompressed 512 byte FAT sector, and the 512 byte DATA sector at the same time?

Re: We need a better name for "Adventure Games."

Whenever I hear the term "adventure" I picture someone picking up a sword and slaying dragons. Wouldn't that be a "big-game trophy hunting game", or a "fantasy safari slayer game"? I would say that real adventures are about solving any kind of bigger or smaller problems that are unexpectedly encoun...

Re: Honest box art

Would an honest box for a Minesweeper clone look like a bunch of soldiers using metal detectors? Yes, except that mine clearing is a painstaking decades-long task, more likely left to civilians, not to soldiers posing with machine guns (and whom are suspectable of having planted mines in the first ...

Re: Mysterious pirate CD with swapped bytes

PPS. All CDROM data sectors (including those on for CD-XA discs) are internally stored inside of 930h-byte CD-DA audio sectors. The bytes are encoded as optical codes (as far as I remember, each code is 10bit wide, with 256 valid codes for 256 bytes, and several invalid codes) (and maybe the optical...

Re: Mysterious pirate CD with swapped bytes

CD-XA can use FORM1 sectors with 800h bytes and error correction, or optionally, FORM2 sectors with 914h bytes without error correction. The sector CRC is optional for FORM2, if the CRC is missing then you won't even see if there are errors. Maybe that's the problem? The burner might have tried to u...

Re: Ideas for compressing BRR samples further

Yes, that's interesting. Two basic questions:
- Is it lossless compression, allowing to restore the exact original BRR data?
- Did you already test different BRR files, including speech and other random sounds?

Re: SNES PCB type database

I wouldn't follow Nintento's naming scheme that strictly... you could hardly say that the RTC chip isn't a special chip because Nintendo had declared the RTC chip being... an SRAM chip? The nice thing about the Special Chip column is that it can contain a human-legible description of what kind of sp...

Re: DSi unlaunch (bootcode exploit)

You don't need the launcher. What you need is being able to load homebrew, if that is working, then the first step should be dumping the emmc chip, and then check if it is corrupted... eg. try if the emmc dump works in no$gba, or decrypt it and use scandisk to check for errors. Btw. what did you do ...

Re: SNES PCB type database

The http://snescentral.com/pcblisting.php does look much better now, with the chipset info added to the board names. One thing is missing are the RTC cips... For SHVC-LJ3R-01 add special chip S-RTC. For SHVC-LDH3C-01 add special chip SPC7110 + RTC-5413. Why are the ST010..ST018 board listed with "0"...
