This is my whole November's #30DayVGMChallenge in a single thread
It was fun. I liked
- researching some composers that I didn't have on my radar
- playing some of these gems to record the footage
- learning about #MiSTerFPGA filtering options & #DaVinciResolve video editing

Now that #MiSTerFPGA's PSX core has SNAC support, let's talk about how it will work. SNAC translates 5V controllers to 3.3V using level shifters. PSX controllers are natively 3.3V so the normal SNAC accessory won't work with them. Also, Blue1 added a dynamic csync/IRQ10 (1/4) 
to one of the 7 SNAC pins so both GunCon and Hyper Blaster guns will work automagically. PSX controllers report their controller ID to the core, which switches modes appropriately. The upcoming PSX SNAC adapters will allow for 2P (or more with multitap). I plan on making (2/4)
new HDMI style adapters (current PSX adapters won't work as they're missing 2 wires as shown in the first picture). The last PSX SNAC feature I plan to have is external DC adapter for rumble. 5V rumble isn't quite enough, imo, as the spec is 7.5-8V. 9VDC is the most common (3/4)
RetroNAS is a tool to convert a Raspberry Pi, old computer or VM into a multi-system, retro focused NAS. It can connect to LOTS of things. Read this thread to find out more, or check the wiki: github.com/danmons/retron…
#MiSTerFPGA is probably the one most people know, but it's only the tip of the iceberg. However if you have many systems including MiSTer, RetroNAS can help you share between them: github.com/danmons/retron…
Do you enjoy retro computing? Windows 95 can't connect to Windows 10 any more, with SMB1 deprecated. But Windows 95 can share files with RetroNAS, and anything else connected to it: github.com/danmons/retron…
PSX on FPGA, update #23:
Timer, Joystick and other things.

#fpga #psx #MiSTerFPGA
Also, I am looking for verilog (or VHDL) dev willing to help me on the project. I think I really need support.
Please share the message, it is important.

I plan to share income from the Patreon, but only after milestones have been achieved (most of the people who helped me before did not deliver a single line of code after weeks (and in the end), I won't share in advance...)
I am looking for people interested in :
CPU:
- CPU integration (or remake)
- Integr. of GTE module into CPU.
- Integr. of Cache/Scratchpad into CPU.
Other:
- DMA / bus impl./ BIOS
- DDR debug
- CD Rom impl. (SW 90%)
- Dbug on FPGA board
- Integr. of other modules
PSX need YOU !

Gather round, folks. I'm going to write a @Foone-style thread about a rather interesting debugging adventure I had during the last days.
So there was this new release of the #ao486 PC clone core for the #MiSTerFPGA emulation system the other day. It was a highly anticipated major release with a 4x increase in CPU performance.
I wrote a thing or two about it here:

I also did some benchmarks () using @philscomputerlb's nice suite. Some of the benchmark programs failed to run, but I initially didn't investigate any further. (I mean, c'mon folks, Doom is playable now, what else could you ask for?)
PSX on FPGA, update #16 :
GTE hardware implementation 86% complete.
Registers 100%, microcode 86%, data path and other mostly complete.

PSX on FPGA, update #17 :
Now 95% done. RTPS / RTPT pass Amidog's test suite.
Remains :
- Only MVMVA instruction. (its two variants)
- Slow down instructions that takes less cycle than original timing.
- Faster DPCT (17 cycle instead of 18).

This is a simulation of the hardware GPU, each frame is 50 clock cycle. See my patreon post ;-)
Please RT like crazy :D :D :D
