RGB-PPU report ,RP2C02 clone in FPGA

Hello all：
I am a fc(nes) fun from china.I have finished to copy all the logic of RP2C02 and add some new functions by FPGA.

Please pardon me that I am not very good at English!

This project start at last year,now it is seemd everything is OK.
At first,thanks to

An EP2C5 FPGA replace the original ppu,it output 24bit digital RGB to a video dac ADV7125,then get analog RGB signal.

RGB values from:http://www.thealmightyguru.com/Games/Hacking/Wiki/index.php?title=NES_Palette

This is my test,I have no RGBS display,I use an AV/S-Video to HDMI converter and a RGBS to VGA converter(GBS-8200) to an LCD Display.
On the left is an fc use UA6528(compatible with RP2C02),on the right is an fc use RGB-PPU(FPGA),the rightmost is GBS-8200 converter.

This PCB is demo,I am designing a new pcb to fit fc,new fc and nes.

Wow. The S-Video picture from this famiclone looks as sharp as a PlayChoice, and that's a good thing.

I noticed your username uses Chinese characters. What shall we call you in Latin letters?

My name in English is "SIYAN CHEN".

Thanks. I've added a note about this in your post headers. Welcome to the forum.

Welcome to nesdev
Very neat project, well done.
May I ask what your degree is?

Nice work on the fpga project. Do you have any idea of how accurate it is compared to a real ppu? (Does it say, run battletoads?)

Quick side note, you might want to put a large image warning in the title for users with slow internet. (Although thats almost moot nowadays I guess)

Also, welcome to nesdev!

Thanks！

I am a Bachelor of Engineering.
My major is Computer Science and Technology.

Thanks!
I have not a battletoads game card right,when I get it I will test.
Do you know any other special games that have more difference between run in 2C02 and 2C03?

This is a good checklist: nesdevwiki:Tricky-to-emulate games

Some of them are just CPU tricky bits, but a number are PPU or CPU-PPU interactions.

Any updates on this Siyan?
