Re: Help to find mistake for Circuit with NO SRAM

You are telling us that you have wired /RD to GND and that it does make it works. What kind of comments are you hoping for?

Re: 8.8 Fixed-Point Numbers (signed) with GBDK2020

Or a chat bot child confused about the human obsession with calculating new numbers. There are so many numbers readily available in the internet, what's the point in calculating yet more numbers? Plus, it's difficult to find good numbers for small talk, everybody is happy when you say that you have ...

Re: 3DS reverse engineering

The Connector Pinouts are all complete now! Except, one pin on Upper Video connector: I haven't found a testpoint (or other signal) that connects to P6.pin26. The wifi pins are documented in the FCCID doc, but most of them seem to have no testpoints on the mainboard (but some do, and there might be ...

Re: Achievement unlocked: human spammers

Where are human spammers? If you mean KayBur's not-from-this-world-posts, that looks like typical state of the art bot behaviour to me, ie. analyze a topic, and try to create a roughly plausible sentence with high probability of not being too much out of context. Like being in a programming forum, h...

Re: What keyboards do you use for programming?

That does very much depend on the situation, you could hardly use the same keyboard for NES and Atari projects. It does also depend on the daytime and seasonal light conditions. And, as we all know, it's a well kept secret what keyboards the top programmers are using.

I usually keep the pattern in the box. I've also tried a bag, but there was a problem with mould.

Re: 3DS reverse engineering

I've recently purchased an Old3DS and a handful of 3DS game cartridges. After all the time that I had spend on dreaming of having a 3DS with english GUI and working top screen and with game cartridges... it was a bit disapointing, the 3D effect can be quickly distracting, the screen is a bit small (...

Re: NDS Cartridge ROM specs

The display controller being SSD1854 isn't quite right. The firmware uses a 1-byte page select command (BYh), but SSD1854 is using a 2-byte command (B0h,YYh). There are a number of similar grayscale LCD chips, most of them having the correct 1-byte command: SSD0852 128x128 would allow double-buffer,...

Re: Help to find mistake for Circuit with NO SRAM

Can you explain what those multiplexors are doing? And what makes you think that the menu could work if the multiplexors don't work?

I've finished the specs for the nds infrared port and pedometers: http://problemkaputt.de/gbatek-ds-cart-infrared-pedometers.htm That was quite a huge project, the SPI commands for the infrared port have been quite harmless, but then I couldn't stop adding more and more specs for the infrared comman...

Re: Learning the 65816 cycle penalties

The 21MHz clock is usually called master clock, mini clock sounds a bit unfamilar ; ) This document lists timings in detail https://github.com/larsbrinkhoff/awesome-cpus/blob/master/MCS6500/65c816.txt DBR, AAH, AAL+XL ; $7e0001 2.58 No, that step should be an Internal Operation "IO" thus 3.58MHz.

Re: NDS Cartridge ROM specs

Hmmm, emulating the Activity Meter? Well maybe - but no - it's pretty impossible to imagine people in wheelchairs enjyoing "Walk with Me" in emulators. But yeah, it could be useful for testing if the transfer protocol really works as expected - and maybe for getting more packet logs including initia...
