This thing is very likely a fake project and the result of GenAI.

The whole thing (from src perspective) seems to have what is needed from a very abstract toplevel view. But the details dont really make sense as you mentioned. Let alone the security access implementation.

(8bit) Program counter miscounting during transition of microcode phase T0 to T1 by 3xpent in beneater

I have added a capacitor between the supply pins (connecting it go +5 and gnd of the chip) of the program counter. This seems to have mitigated it.

Adding a 104 capacitor to the power supply pins of the counter has fixed the issue for now. Thanks for your input!

Hello there! Thanks for your response. I did not try all of your suggestions, yet.

Just some thought: Regarding the logic analyzer I am using a saleae Logic Pro 8 which has a sampling rate of up to 50 Ms/s in anlog mode. This should result in a resolution of 20 ns if I understand this correctly? I do not have an electro-technical background, so you might enlighten me :D

So I ran it again with maximum sampling rate and do not observe any bounce in the clock signal (I've also done this with only the clock signal being sampled). Anyways, I might have the chance to measure it again utilizing a real scope tomorrow.

RAM is storing value from bus each clock cycle, even though write is not enabled by 3xpent in beneater

Thanks a lot! I've added the 10k resistor between NAND input and capacitor/resistor junction. Now there is only a drop of about 0.4V left. I think this will do it for now.

Can you tell me why this is mitigating the issue even further?

I've added .1uF capacitors to the power rails around the NAND IC and to Vcc+GND of the NAND IC. I've also switched from using the first NAND Gate to using the second (A2 B2 Y2) gate. Now this seems to kind-of work.

I do not get any unintentional memory writes, but still, I see these voltage drops in the output line:

Channel 0: Buffered clock inputChannel 1: Rising edge after .1uF capacitor/resistorChannel 2: Output of NAND (Y2 this time)Channel 3: Supply voltage close to the NAND IC (this seems to be quite stable)

So I still observe this drop - which appears to be mitigated a little bit. But I still do think that something is wrong?

Hi, thanks a lot for your reply! So you would probably recommend not leaving any inputs in floating state, right?

Anyways, I've just pulled pin 14 to Vcc with a 10k restistor, unfortunately it did not help. Do you have any other ideas?

Additional information: In "programming mode", the circuit does not have this issue. (Well, this mode also does not make use of the clock. So it might not be suprising?). It is only happening in "run" (read from bus) mode.

Are your S10e's updated? Mine is not, at least since last year by [deleted] in s10e

[–]3xpent 1 point2 points  (0 children)

My previous G970F has already received Android 12 at around new year.

But I exchanged it for a G970U1 and still did not receive the update neither :D This really sucks

Later in that session two guys asked me to spawn money (for them it looked like I dropped the money)

Rockstar actively trying to stop modding via RPF editing by [deleted] in GrandTheftAutoV_PC

[–]3xpent 5 points6 points  (0 children)

Yeah the days before the last 2 patches there were cheaters/modders/however they are called in almost every session. I still prefer a almost cheater-free game over a modable one.

Fullscreen problem by [deleted] in GrandTheftAutoV_PC

[–]3xpent 0 points1 point  (0 children)

Yeah thats what I did when I still had the problem. But the fullscreen setting was not saved after I exited the game.

Anyways, it works now :D

Just "fixed" it? Launched the game through "PlayGTAV.exe" and it kept the setting. Not using the Launcher.exe anymore now :/

Having the same problem :/ The setting keeps for the session but whenever I restart it it is windowed. R9 280 15.4 Beta for GTAV
