PAL Chips, RGB Support, and Shipping Timeline

by Daniel G

PAL Update

The NTSC / PAL clock switch has been tested and PAL output appears to be working correctly.

Output with NTSC chips (RP2A03 / RP2C02) and switch set to NTSC:

Output with PAL chips (RP2A07 / RP2C07) and switch set to PAL:

We will also have a small number of PAL chips (both genuine and clone versions) available for sale by special request.

RGB Update

The routing of the RGB traces has been improved dramatically, and the previously faint vertical striping that had been visible (only with RGB output) has now been significantly reduced. This phenomenon is also known to vary somewhat with different RGB chips, but it’s very reassuring to see so much of an improvement in our test setup. On our RGB CRT monitor, vertical striping is no longer visible at all.

RC2C05 Support Added

We’ve added support for RC2C05-01 / 02 / 03 / 04 RGB chips! There’s a tiny switch underneath the PPU socket that only needs to be flipped if you’re using one of these chips (RC2C05-99 chips should not require this). Don’t worry, all of this information will be in the printed documentation as well.

There’s one big caveat here: We don’t have an RC2C05 to test. If you have access to one, please contact us!

Production Update

The TinyNES Main Boards have finally entered production. A huge thanks goes out to everyone who helped with testing!

Timeline for Shipping

We expect a first-article Main Board to evaluate in 3-4 weeks, with the full production run arriving 1-2 weeks later if everything goes smoothly. Finally assembly will take another 1-2 weeks.

I know that our shipping targets have slipped a few times, so I understand if anyone is feeling frustrated about that. We certainly are. We’re doing our best, and we will continue to provide regular updates for as long as it takes. In the meantime, if you ever have any questions, or just feel like checking in, please don’t hesitate to reach out.

All the best,
