			Most adapters will not support advanced CRTC tricks like in Relentless or even Ghosts'n Goblins. However the "[https://kaicolabs.com/product/kaico-sega-saturn-2x-line-doubler-hdmi/ Kaico Sega Saturn 2x]" adapter does properly support CRTC scrolling like in Ghosts'n Goblins - only the very latest, advanced tricks like in Relentless will not fully work but at least display a picture with stuttered scrolling. You might need to update the firmware and adjust brightness settings with the software from the Kaicolabs homepage to properly use it. The adapter can be found for around €30 in online stores (as of 2025).

			Another advantage: The adapters are so small that they can easily be placed inside the CPC to add an internal HDMI output.

	SCART to HDMI converters are the cheapest and most simple solution. Make sure they (really) support RGB and not only composite video, like the cheapest SCART to HDMI converters usually do. RGB SCART converters start at around ~~30€~~ (~~2022~~). They will usually work and you will probably first think, that this is perfect, but they can add a hefty lag to your screen, some add up to 120ms (or 6 frames).

Also CRTC tricks often do not work so some games won't be playable.

	This DIY project by forum user gregg is based on the Raspberry Pico and (as of November 2024) the only solution that supports most (all?) CRTC tricks. Even games like Relentless that do not render properly on any of the other scan doublers are perfectly playable and absolutely smooth. Hardware and software are publicly available and the scan doubler can be built for less than €30 (€10-€30, depending on shipping costs for the parts). Assembly should be doable for anyone with average soldering skills.

	[https://www.youtube.com/watch?v=2CnsQBGAuos The new star on the horizon.] An open source project, that combines a Raspberry Pi with some custom logic, to convert signals from home computers and home consoles to HDMI. For almost every computer there is a more or less different version of the board. You can build the RGB2HDMI yourself or buy a finished version, e.g. on sellmyretro.com . It's features are even beyond those of the OSSC and Framemeister. Its total price is somewhere between the GBS and the OSSC, depending on where you buy it. And its tiny. Its biggest disadvantage is, that you need a different version of the board per console or home computer (well - some computers share a similar signal, so e.g. for the BBC you can also use the CPC version, but e.g. an Amiga or an Amstrad Plus each need another converter version). Screen lag has not been measured yet for it, but it seems to be very low.

			The only downside would be that it only supports the Amstrad CPC, so if you own other computers (or even a Amstrad Plus or GX4000), you still need another solution.

	Especially the GBS8200 is easily available and incredibly cheap and if you know how to solder, the GBS Control mod is easy to do.

And that's of course also the downside: you need to solder - and probably also 3D print a case for the GBS.

			Update: Some sellers have adopted the GBS Control firmware and offer full products based on the GBS 8200 chipsets and the GBS Control mod. The price is a bit more than building one yourself - but still A LOT cheaper than any other (good) scaler solution. On the positive side it also already includes a case and HDMI output. Offers can be found e.g. on Amazon or AliExpress. Search for "GBS Control". No test has been docuemted so far with a CPC, so there's still a risk that the hardware behaves differently from a self-built GBS mod.
