Ciao! I’m Marco, a YouTube content creator on the channel MarcoRetro (MarcoRetro316). I am a CRT hobbyist (team RGB) and probably best known for my coverage on downscaling. Stop by my channel and check out the Downscaling Chronicles playlist to follow my journey down the forbidden 240p rabbit hole. I am on Instagram/Twitter (X) though I don’t frequent these platforms all too often, and the best way to reach me is in the YouTube comments or through mutual Discord servers (MarcoRetro316).

The Barco Folsom Research ImagePRO is a presentation scaler encased in a hefty full rack length metal enclosure. A fellow downscaling enthusiast on shmups who goes by KTown, discovered that it can output 240p. https://shmups.system11.org/viewtopic.php?t=77173 It has a wide range of analog video I/O’s that supports composite, S-Video, component and RGB via BNC and HD15 […]
Update April 11 2026: Official OSSC FW 1.20/1.21 allows flashing a secondary firmware on OSSC hardware version 1.8. This means that the OSSC Line-Multiplying FW can be used for upscaling, alongside VoidScaler as the secondary FW for downscaling. See RetroBobarino’s post and video for more info: https://retrorgb.com/voidscaler-firmware-v0-91-ossc-downscaler.html VoidScaler is a custom firmware created by e8root […]
The Extron DVS 605 is a robust scaler that can be programmed with custom resolutions to downscale to a CRT. It has inputs and outputs for both digital and analog video, a crisp picture, fluid image controls and about 1 frame of lag for progressive inputs. To help downscaling enthusiasts get the most out of […]
There are several ways to output 15KHz emulation via GroovyMAME and RetroArch without an external downscaler such as CRTEmudriver for Windows and the Linux distro Batocera. These are very solid options to play retro games in their native resolution on a standard definition CRT, but more options are always welcome. Groovy MiSTer by the late […]
The Kramer VP725DS and VP-747 are switchable scalers that can be programmed with custom resolutions. Reports on the Shumps forum suggested they can downscale to 240p, but not without quirks. Top row: Kramer VP-725DS. Bottom row: Kramer VP-747 Switching and Scaling Credit to Kumulus 28 for discovering 240p output on the VP-725DS The VP-725DS is […]
The ‘Extron EDID Method’ is a way to downscale HD content to 15kHz using a compatible Extron scaler on the Product Configuration Software (PCS) list, though this does not guarantee compatibility with this method. The PCS software communicates with the scaler to upload a custom resolution via an EDID.bin such as 240p. Downscaling to 240p […]
Ramapcsx2’s open source GBS-Control offers CRT enthusiasts an affordable, low-latency option to downscale modern media to a standard definition CRT using a modified GBS 8200/8220 scaler. While basic soldering is required, pre-built units are also available online. For the purpose of downscaling, the GBS-C handles 480i/p input and 240p output via analog video. Some sellers […]
Following the previous VGA reproduction card for the Loewe Q24/Q25 chassis, DJCalle has reproduced another VGA card for 100Hz Loewe CRT’s for the preceding Q23 chassis. The VGA card bypasses the 100Hz upscaling circuitry, so VGA inputs will display natively in 480p without lag or nasty image processing. The vast majority of Loewe TV’s with the […]
Firmware 0.78 for the OSSC Pro has been released, and although I have mostly focused on downscaling, all OSSC Pro users will benefit from improved Scaler Mode frame locking and some other UI improvements. Here is the full Firmware 0.78 changelog: * 1920×1440@60 input support added for both analog and digital sources * 1152x864_75 […]
Micomsoft’s XRGB-3 may not be as highly regarded as it’s successor, the XRGB-Mini Framemeister, but firmware versions 2.1 and later had a feature that its little brother did not; a ‘Low Resolution’ mode that outputs 320×240 (240p), and 640×400 (mid-resolution). Several shmups forum members reported that the XRGB-3’s 240p output looked pretty bad and not […]
