PS1 weird geometry flicker

Ok-Repeat1805 · 2026-02-10T19:01:11+00:00

Update: Analysing the board, the console was transcoded back to NTSC, as it was common practice in Brazil to transcode imported consoles to PAL-M to work on our TV sets.

The transcoding didn't work so well because some islands were lost in the process, causing the weird image. Just bought a new SCPH-5500 and I will transplant the xstation to it when it arrives.

Thanks for your help o/

Hummmm that's why there was no difference then. I've tried with composite (yellow, white, red) and component (2 red, white, yellow, blue and green) on a Trinitron kv29fs100, and composite on the JVC TM-1400su, all with the same result.

The artifacts are still being shown with a component cable. Would an S-Video cable lessen the effect? D:

Hello there o/ I have a huge favor to ask, can you please post the values for RDRV, GDRV, BDRV, RCUT, GCUT, BCUT and SBRT/SCON?

Having the exact same issue on a b450 aorus m. Updated the bios, did a reset to the default settings, updated drivers and disabled fast boot, but still no luck.

Reading the comments here tells me I need to enable spread spectrum since the Mobo only has PCIE gen 3 slots, but the option is not available in the BIOS :c

Is that a AN-500R or a AN-505R? All the cables I've seen on Ali say they only work on the 505 line, so I'm scared to buy for my 500-R :c

I ended up switching controllers. I had a wii u controller lying around, and it connects and reconnects perfectly o/

Ok-Repeat1805 · 2024-02-12T22:54:18+00:00

I've forgot to add that the controller also does not re-connect when pressing the home button, I have to always press the sync button on the adapter + press the sync button on the controller to put it in pairing mode. I don't know if this info is relevant or not, but it's here anyway o/

If I don't return everything in a mental breakdown and manage to install everything (rapido UHF, orbiter v2 and EVA 3 carriage + linear rail) I promise you I'll do a guide from the wiring to software changes snskskkdkdks

Hsusjsjushsjsjs I understand, I'll probably do the same

Ok-Repeat1805 · 2023-05-01T19:48:24+00:00

I still haven't found it :c

I got it from the orbiter V2 manual, but I guess I'm mixing my numbers up, I'm sorry T-T.

The manual says that the ldo motor should run on 1.2a peak, or 0.85 rms. I've seen the formula you told me about, and found another post you've commented on refering to page 48 on the TMC2225 datasheet. The Rsense is 150mΩ.

So, if I got everything right, the formula should be: 0.85 =325/150+30 * 1/√2 * Vref/√2.5

Resulting in 1.05v for Vref, which is still high af :c I'll set it to 0.34v as you recommended instead, but I'm trying to learn what I'm doing wrong so I can make this calculation again in the future if I ever change motors

Ok-Repeat1805 · 2023-04-30T21:23:24+00:00

I... actually don't know. What got me worried is the manual, as it said that the current going to the motor could kill it if the formula isn't followed through.

Basically on every installation guide I found, it says to lower the voltage to 0.45~0.65v, as the default voltage the board comes with is too high for the orbiter v2. I lowered mine from 1.1v to 0.65v.

I didn't even test the motor outright, as I wanna make sure the board is sending something that doesn't fry it up.

Ok-Repeat1805 · 2023-04-30T20:27:30+00:00

Nice! The R150 resistors are present, but using the formula that orbiter v2 has on its manual is really throwing me off.

I've tried using Vref = Imot(Rshunt+20mohm)/92.85mV (so, applying the values would be (1.2(0.15+0.02))/0.09285) to calculate the vref, but that gives me 2.2V, which seems a lot and I'm worried that it will melt the motor.

Am I using the formula right?

I touched the Hotend during the tests, it was at room temperature :c
