Wonderswan shoutbox quest for the pure flame (repro madness?)

I probably already have compatible chips

 

Good to know. With some effort we can probably get this thing going.

 

@Digmac Turns out I don't. Gotta wait on the two I ordered.

@Bad_Ad84 I just need that SRAM chip or a compatable one from the pts-0101.
I need to see if my programmer even has a 48 pin slot.

 

Docodemo 3 has an undocumented pcb of pts-0111

Absolutely nuts. This isn't something we anticipated for sure. I wonder if all Dokodemo 3 carts have the 111 PCB.

 

After talking with trimesh and testing out some pins, it seems like the pts-0111 is elecrically the same as the pts-0101, including the rts. We likely have a candidate for a WW donor board. This is even better than the pts-0123

 

This is fantastic news tofu... unless you are a dokodemo hamster cart.

 

Just perhaps people won't have to drop $700 on a WonderWitch after all heh. Buy all the hamster carts! Perhaps there's a little more WS madness here than we first thought. WW & JSS that won't break the bank.

 

sram ordered. talking with @Bad_Ad84 found a sram that we could use. And turns out if we just offset the ram by one row I'll only need to solder 6 wires. Also helped to better understand how these things work, thus reducing the amount of solder work I thought I had to do.

Testing out bigger sram on the game first. then will try a different rom.

 

Cool. In my searching for info in the undernet I cam across someone doing a homebrew shmup that looks pretty good. Same guy also dumped the wonderwitch firmware too.

Is that the same guy who did the bug fixed JSS? Who knows. We could have two shmups on the way for the WS. You're doing awesome work Tofu.

 

On the pts-0101 board 3 a pins are going somehwere while one is connected to vcc.
a15 leave lifted above the we pad, and bridge a15 to vcc as they are right next to each other.

the 32sram being centered - one of the extra rows on top and on the bottom.


Figuring out where to put a11, a3, a4

 

You can't leave them floating. The extra address line are what give you access to the extra space. They need to connect to the mapper chip.

/we need connecting to vcc

 

I'll look closer at scans, maybe those points run under the chip.

 

You cant leave any address lines floating (or any lines in general, they need a defined state). The connection is probably under the chip so you cant see it.

 

-deleted for old wrong info-

 

Looked over pts-0111 again. Scraped away some of the white mask around the SRAM pins.
WE, after two vias, goes to pin 46 of the mapper.

Looking here http://splash.myweb.hinet.net/

Seems to be a cart pinout, and instructions on how the larger SRAM is enabled as well.

How to make Bandai 2003 support 512Mbits ROM/SRAM?

Port 0xc0, 0xc1, 0xc2, 0xc3 can switch 256 banks * 64KBytes per bank = 128Mbits. On Bandai 2003 there are two GPIO pin controlled by port 0xc?.

One Piece treasure wars 2 cartridge use these two GPIO to control two LEDs. If we use these two GPIO to switch two address pin on ROM/SRAM,

we can switch 4 different 128Mbits -> 128Mbits x 4 = 512Mbits."
