If you're shopping for gaming replacement parts modding, the decision usually comes down to one question: do you want a cleaner analog signal or a true digital HDMI output? The NTSC To RGB Output Module Chip RGB MOD Kit and the PS2 Fat Digital HDMI Kit take opposite paths, and they are priced accordingly - $26.69 vs $50.93. The lower-priced N64 mod refines the N64's RGB output, while the higher-priced PlayStation 2 kit moves a PS2 Fat's video directly to HDMI.
Quick Verdict
If you own an NTSC N64 and want sharper, cleaner RGB output for a CRT or an upscaler like the OSSC, go with the N64 RGB MOD Kit. If you own a PS2 Fat and want true digital HDMI without relying on an external converter, the PS2 Fat Digital HDMI Kit is the more involved but more transformative mod.
N64 RGB MOD Kit vs PS2 Fat HDMI Kit at a Glance
| Product | Listed Price | Core Job | Main Catch |
|---|---|---|---|
| NTSC To RGB Output Module Chip RGB MOD Kit | USD 26.69 | N64 RGB output module using a THS7374 amp for clearer and smoother images | Stays analog; needs an NTSC N64 and an RGB-capable display path |
| PS2 Fat Digital HDMI Kit | USD 50.93 | Digital-to-digital HDMI output for PS2 Fat with built-in OSD and video modes | Requires good soldering skills; PCB and flex must be fitted |
Where Each Product Wins
- N64 RGB MOD Kit wins for N64 owners with NTSC consoles who already have an RGB monitor, N64 RGBS cable, or an OSSC setup. It costs less to enter and keeps the analog chain simple.
- PS2 Fat Digital HDMI Kit wins for PS2 Fat owners who want direct HDMI output with more controls. It supports 480P and 1080P output, includes an OSD menu, three video modes, and six aspect ratio presets - all inside the mod itself.
Product Notes
NTSC To RGB Output Module Chip RGB MOD Kit

The N64 RGB MOD Kit is not a universal HDMI solution; it is a focused analog upgrade. It uses a THS7374 amp to deliver clearer and smoother images, and you can connect it directly to an RGB monitor using an N64 RGBS cable or to an OSSC using an N64 SCART RGB cable. At $26.69, it is a relatively low-cost way to get a much better N64 picture on the right display. The limitation is in the name: this is an NTSC-oriented RGB module, so it suits an NTSC N64 setup. It also stops at analog output, which means HDMI still requires an external upscaler. If that display chain is already in place, this mod makes strong sense.
PS2 Fat Digital HDMI Kit

The PS2 Fat Digital HDMI Kit is aimed at a complete output change. It takes a digital signal from the PS2 Fat and sends it out as HDMI, with support for 480P and 1080P output. The built-in OSD adds control over three video modes - Mild, Standard, and Dynamic - and six aspect ratio presets, making it a much more self-contained mod. The hard part is installation: the kit includes a PCB and flex that need good soldering skills, and there is no paper manual included. You'll contact the seller for installation instructions after receiving it. If your PS2 Fat is ready for clean HDMI and you can handle the soldering, this kit rewards patience with a genuinely digital output.
Final Choice by Use Case
If you mod an NTSC N64 and want better RGB for a CRT or OSSC, the N64 RGB MOD Kit is the clear pick. If you mod a PS2 Fat and want direct HDMI output with built-in menus, the PS2 Fat Digital HDMI Kit is worth the extra cost and effort.
