Need helps to how to interface PIC16F877A with graphic LCD

The pinouts of the GLCD is same as yours DB0-DB7 on pins 7-14 and CS1,CS2 on pins 15 & 16. I normally use 4.7K to 10K for MCLR. If the MCU doesn't reset properly, I'll add a 1uF from MCLR to GND. Are you using SK40C to interface the GLCD? May be the clock is too fast...

I solder my own board with 20MHz crystal, still same as SK40C. So, my pin configuration is confirm. Luckily, I found 10K on my storage, I though I don't have. Then, I will follow Brian tips to exaggerate the delays.

Btw - those Graphics LCD such as KS0108 type or the ST7920 are very slow in rendering graphics. Take note of that if you have to make mini-games out of them.

I tried using a frame-buffer and all I left is only 9 frames per second. Many of the youtube videos showing microcontroller games with GLCD with very, very limited framerates.

I'm not trying to do animation yet, just to see what can do with GLCD.
