00 39 is a different issue, that's when the Gameboy crashes. When the MM1134A fails, the SRAM chip is never instructed to output any data. This gives the value 1A or 2A repeated everywhere. This is the value of the opcode that is used to read from SRAM, which stays on the data bus because of bus capacitance. (The traces and metal parts in the connectors are acting as capacitors which store this value for a short period of time, but long enough for it to be picked up again.)

If you look just slightly higher, you'll see a face with a large fake moustache.

Please keep thread titles descriptive. (Not just "wanted") I've edited the title to be overly descriptive.

Should I waste some more time on this and list which bots are crawling the site too?

You could click the chipmusic.org link in the breadcrumb. (Between the thread content and the reply field.) Or press the home button, if you're one of the people still using a computer with a keyboard.

Topic: Extended online stats (9 replies, posted in Rules & Announcements)
Because of this thread I made probably the most useless update to cm.o so far, but it might still some people's curiosity. There's a text below the list of users on the right side of the page. This used to show only the number of guests and and logged-in members. It now also bots and spammers.
Explanation of the categories:
Guests: Users that are not logged in and also don't fall into any of the below categories.
Members: Logged-in users.
Bots: Sessions reported as coming from bots. These are mostly legitimate search engine crawler bots. This includes a certain ChipMusicHeartBitsSpidy, btw. 
Bot dupes: I noticed that some crawlers (especially Yandex. Edit: I mean Baidu...) created a lot requests from different IP addresses which created a lot of unused sessions, which would sometimes boost the guests numbers really high. Those are now sorted as duplicates.
Spammers: This indicates that a session has been blocked by one of the various automatic spam detection methods in place on cm.o.
A session can only be in one category at a time.
Now you know.

Yep, trying to clear up the confusion with some rudimentary bot detection. Next project will be to add a count of the number of spammers as well. Maybe it will turn out the number of real guests is 0.

Nanoloop 1.0Why does the cart say "SAM"?
Wouldn't it make more sense for it to say "Oliver" or something, seeing as that's the name of the guy who wrote it iirc.
He mostly likely bought those cartridge off of pirates. Getting a custom imprint costs money. Most likely the SAM is either the name of the company manufacturing the shells, or a distortion of game. Previous cartridges have said game, but Nintendo might have sent legal threats for even printing "game" on a pirate cartridge.

It could be. You should probably be replacing it anyway, so...

Re: gone (8 replies, posted in Nintendo Handhelds)
Do you hear the po-ling sound if you wait the time it normally takes for the logo to scroll down the screen? Can you adjust the contrast when the EMS cartridge is inserted, or does it always stay the same contrast?
My theory is that the PCB isn't properly seated inside the cartridge and shorts something out when inserted to a DMG. Open up the case and lift the PCB and put it back. Be careful when you lift the PCB, as it may be stuck down with double sided adhesive tape.
I'm also noting that that is an EMS 64M USB cartridge in a shell originally designed for the older EMS 32M cartridges.

Re: WTB: 2x GB Flash Carts (must have SRAM backup capability) (2 replies, posted in Trading Post)
Just a suggestion. EMS carts are multi ROM capable. If you want, I can hook you up with a ROM that can run both LSDj and mGB from a menu.

Re: MGB MIDI channel usage beyond 1-5? (16 replies, posted in Nintendo Handhelds)
Yeah, like I said, quick hack. I probably only made it print the channel names on start-up and not in when returning from screen off. Again, sorry.

Yes, the nitro hacked version accepts the other channels, but each proceeding five channels must be on separate cartridges.
Yes, I made versions that listened to channels 1-5 (as usual), 6-10 and 11-15. But this was just a quick hack. As I later figured out, these versions of mGB didn't work as expected. Sending MIDI to channels that outside of the individual ROM's channel range would still crash the program, so it was useless for connecting 'boys in parallel anyway. That's why they're not available for download any more. Sorry.
Maybe one day I will actually get to finishing my own MIDI ROM, which will not have this problem.
