Re: N64 HDMI converter thread

Haven't finalized the direct modes. Buffered modes are 480p and 1080p. I'm still considering what to do about PAL with its extra lines, whether to resample it to fit 480 or find a nonstandard mode. I have done some tests with audio - rough, unfiltered audio is coming thru HDMI now. Next rev came in ...

Re: N64 region mod

Read the MX8330 and MX8350 datasheets 8330 is configurable for either Rambus or colorburst based clocking. In older mobos it's used twice, configured differently. 8350 combines two of them into 1 die and removes the unnecessary functionality. You can either use a fpga PLL to directly drive the OSC s...

Re: N64 HDMI converter thread

Good news: first HDMI proto is doing its thing! I just got the RAM working earlier today. I have some errata to fix with this board, but it works well on my big TV. No processing or anything, this is as simple as it gets. While this TV has about half a second of lag thru the composite analog input, ...

Re: N64 HDMI converter thread

It doesn't replace anything. It sits under the AV out port, but doesn't require any changes, except for a small notch in the lower case half. It's possible to have mini-HDMI and the AV cable both plugged in.

I will get a pic sometime.

Re: N64 HDMI converter thread

I don't have the FPC fabbed yet for the connection. So I'm hand wiring the first proto:

Re: N64 HDMI converter thread

Are you going to do any sort of bundle for people looking to buy both a HDMI converter and a 64Drive?
Doubtful, since I am selling the HDMI mods through resellers/installers, not directly.

Re: N64 region mod

pin 8 of the PIF is the PowerGood input, generated by a dedicated POR IC just above the PIF. It's basically a comparator, that goes high after the 3.3v rail is stable. You can cut this trace and drive it via some FPGA i/o. Such as when your PLLs are locked and ready to go. You may play around with t...

Re: N64 HDMI converter thread

Yes and no. It's a simple question with a lot of answers. Right now I plan on having two main modes: normal and direct. Normal involves buffering at up to 0.5-1 frame of delay to allow the TV to continously sync up to the generated signal, no matter what the N64 is doing. As an example, many games s...

Re: N64 region mod

I would probably use a CMOS switching chip instead of relays. You can get one for $2 that muxes up to 8 signals at once. But yes, to have both region support you would need a NTSC and PAL PIF installed and switchable. Also, the clocking is different on PAL units than the rest. While all consoles use...
