I am still working on that stuff. I've written a DS Download Play clone, and a DS Uploader for the opposite direction (and step-by-step figured out more details on each transfer side needed to get them working). The tables and descriptions in gbatek for Nintendo Beacons and DS Download Play were far...

Please stop!

Explaining that armored females aren't good because you prefer to identify more of their anatomy... it's one thing to say that in 2015... but few would expect to hear somebody to repeat that detailed considerations in 2020. What was your goal when starting this thread, female empowerment, voyeurism,...

I can't see the similarity between C and BASIC though.

For, if, else, while, return? Or asking the other way around: Can you see any differences between C and BASIC?

C is the same as BASIC, with the english keywords replaced by punctuation marks (back then - after the 8bit era - those punctuation marks were considered to be refreshing, cool, funny, and more much innovative than BASIC keywords). Historically, BASIC was often implemented as Interpreter language. I...

As far as I understand, the normal framectl values are... clarifications for RXheader[00] flags bit0-3 (frame type): 0Ch: MP host CMD frame ;framectl=0228h=Data, FromDS, Data+CF_Poll 0Dh: MP host CMD ack frame ;framectl=????h 0Eh: MP client reply frame (data) ;framectl=????h 0Fh: MP client reply fra...

Well, that can be useful, I am sure that everyone here is occassionally using such "templates" (be it via copy/paste or whatever). I don't feel like needing a special tool for that stuff... but I also don't feel offended by people using or sharing such tools. What is wrong: It should have been poste...

Why would they bother providing a specific bias voltage on pin 24? In some other (battery-less) boards they just connect pin 24 to ground. Does the RAM not work if pin 24 is grounded? If it is a Vbat/VCC voltage comparator (as in MAD chips on SNES) then it should be vice-versa: "RAM not working if ...

I have spotted a few more RAM-halfwords that get changed by hardware. Nintendo's software does init/change several values: [480xxxxh]=5A5Ah/A5A5h ;-initial dummy WifiRAM memfill values [4805F70h]=FFFFh ;\ [4805F72h]=FFFFh ; set to FFFFh by software [4805F76h]=FFFFh ; [4805F7Eh]=FFFFh ;/ The hardware...

1M ohm output looks extreme, especially with the 1K ohm pulldown... though it might be intended for Mic In (rather than Line In)? Most tape recorders did also have some volume regulator for recording (don't know if that's lowering or amplifying the incoming signal though). I don't remember ever havi...

Looks good! Thanks for the info! setting bit0 blocks W_BEACONCOUNT IRQ14 until W_US_COUNT matches W_US_COMPARE. From what I can see, W_US_COUNT.bit0 seems to be always zero when reading. If bit0 is write-only, I wonder if it does affect any other registers... like setting/clearing/acknowleding/reloa...

Are that official demos or homebrew demos with WR bit set for reading? If WR can be set for reading... I don't know what distinguishes between reading and writing... For reading, the hardware would transfer some bytes, and then set the DRQ flag, for passing on the data to CPU. For writing, it should...

What should be updated/clarified about NDS Wifi in gbatek? As far as I know there are some recent findings about local multiplayer mode? The most recent NDS Wifi additions (from last year) in gbatek were on the packet format, including some details WPA/WPA2 packets (I had hoped to implement that in ...
