Questions that do not deserve a thread

Can any hdmi lag testers be programmed for an unusual refresh rate like 59.18hz?

[Galgomite]

I asked the above because I’m trying to work out if TVs with excellent input lag measurements maintain those numbers when refresh rates are off, as is the case with many game consoles.

Does the PC-Engine Shooter Collection for the PSP has a replay function?

Recently got my first Saturn 3D controller, the stick on mine isn't all that smooth, hard to describe but kind of like there is an extra resistance half-way to the edge. A bit like a quite used N64 stick. Anybody know if that is just due to the used condition or if these are always like that?

Trying to understand what's the deal with my trusty old modded PAL PS2 (SCPH-39004) via S-video to a Panasonic WV-CM1450/G. 1st party Sony cables used, no cheap crap.

Said PS2 has a black and white picture after the initial boot screen once it gets into a game. That's when the monitor is set to NTSC mode. In M-NTSC, I get colours without the green channel. I've only tested NTSC games as I don't own any PAL games for the system.

Japanese N64 (albeit also RGB modded, if that matters) via S-video shows no problems. Nice vibrant colours. Same with the AV Famicom in composite.

Is there something special with PAL PS2 S-video? Or is the DMS3 modchip at fault? I've used the very same console with other CRTs without any issues for 20+ years.

Older PS1 revisions, 5xxx and earlier (IIRC) are like this as well. It's a feature of these systems, not something wrong with your setup.

PS2 modchips usually had various compatibility settings and it seems yours does as well. http://ps2.x-pec.com/dms3_operation.html

Yeah, the DMS3 menu is familiar to me. Because without PSX fix turned on, the picture is squished with lots of empty space in the bottom for PS1 games.

I've tried every possible video fix combination, including PAL60 that wasn't listed on that page, and not a single combo gave me 60Hz with proper colours with this specific monitor.

As a bonus test, I used an RGB SCART cable with a S-video transcoder and 'lo and behold I get the right colours in 60Hz just like that.

Maybe I need to try a different firmware version with the modchip.

I noticed tink4k and maybe morph using very high sample rate for consoles like nes then "decimate" them by about 10 to go from 3410 to 341 which is the correct one for NES or so.

However, the ADC TVP7002 does not allow decimation like that to my knowledge, only allows many samples. I get it that thousands of samples are better for sharpness (oversampling)...

My question is: how is decimation happening? where does it happen, in FPGA or ADC itself? I really want to understand the operation and if in FPGA which IP or block is used.

thanks!

did anyone try to feed csync signal to lm1881 stripper? i know it takes composite or luma then strips the csync and outputs it, but what if the input was actually an already clean csync?

[Xan]

Yes, didn't notice an issue. I recall reading that it could shift the image a bit or something though, so I avoid it just in case. Perhaps a scope could show if it does something to the sync signal?

I think I have done this before and it basically just passes (at least what you see on your CRT monitor) the sync signal right through. Noticed no interference or the image gain decreasing/increasing.

If you have test equipment, maybe see if there’s an alteration to the sync pulse/sync tip/etc… but I don’t believe it is much cause for concern

Not exactly a hardware question, but a search for "tariff" returned this thread.

I bought some books and paid the seller's PayPal invoice. It wasn't until after that it hit me, oh shit, international order, tariffs. I can look up and apply the percentage, but does that go to the total paid items + shipping, or just the item price? How do I get notified when it's time to pay? What payment methods can I use? I'm not experienced in this, so getting an idea what to expect would take a load off.

Will depend on what carrier is doing the work on the US side. Keep an eye on tracking for when it's in customs and see if it stalls out- the seller may have marked them as a gift or books may not be included? Nearly impossible to actually go to .gov websites and read about what has exceptions and what doesn't, unless you've studied law.

DHL is the only carrier I've dealt with DDU tariffs with, and they sent me an email and a letter. Of course they were asking for literally more than the items cost, so I just ignored them and took it as a loss. For some reason, they delivered the item anyways...

That was for the struck down tariffs though. Should just be 10% on the item cost these days (don't think shipping is included, but I'd just assume it is to prep for a worst-case scenario). If it's a private courier service like DHL/UPS/FedEx though they'll also charge you ~$15 in processing fees for taking care of the paperwork for you.

If the international eBay seller uses UPS to deliver said good/s to the USA, UPS will e-mail you with the proper tariff amount to be paid before it can be delivered to the said recipient -- sad but true currently in 2026 nowadays. If the eBay buyer doesn't pay the requested tariff charge within a certain amount of time ($23.00+ tariff charge upfront easily), then UPS will have the eBay item shipped back to the original country that it originally came from. Gotta thank Trump for passing the tariffs indeed for those residing in the USA -- it's business as usual these days.

If an American eBay buyer buys an eBay item sent from Spain to the USA, the Spain based "Correos" international shipping courier won't charge any tariffs on it and USPS will take over & deliver the package to the recipient's address once it's received within the USA. True story, folks.
