ALL PCE/TG16 game in one cartridge (EXCEPT SF2)

Nice work

woshizyt: Is it going to be able to handle Populous as well? That includes 32k of ram on the card, right after the 4mbit range of the rom.

 The SF2 mapper is dead simple. If you're familiar with Famicom, it's not unlike unrom and other such simple mappers in it's simplicity. The game uses the whole lower 8mbit external address range (typical hucard range). The bottom 4mbit range is fixed to the first 4mbit of the rom, the upper 4mbit of the 8mbit hucard range is used for swapping in 512k(4mbit) banks. So it's a 4Mbit+16Mbit format. Writing any value to 'external' address range of $1ff0 to 1ff3 selects which 4Mbit segment of the 16Mbit segment gets mapped into the upper 4Mbit hucard area. So $1ff0 = bank 4Mbit #0, $1ff1 = bank 4Mbit #1, etc.

THANKS ! I will continue research.THIS card don't include 32K of ram .so Polulous perhaps coundn't run.This card have a CPLD .and the mapper logic can add convenience.
The SF2 mapper logic block diagram could be this,right?



by the way ,is it possible add a save ram chip into this card?I buy a TENNOKOE BANK 2 ,find inside have a HU6260 chip and a SRAM.
I couldn't know how HU6260 chip work .

 Yes, that mapper logic looks right. Save chip? You mean the BRAM that's in the boosters or CD addons? The tennokoe bank card just allows you to transfer to and from BRAM. Games don't save directly to the card (for obvious reasons of it being a hucard).

 Emulating BRAM in hardware isn't too complicated. BRAM is 2k of directly accessed memory (no I/O ports). It resides at bank $F7 which is external address range $1EE000-1EE7FF. It's not mirrored. But access to the ram is locked. And unlocking/locking is done by ports. Two ports. The unlock port is $1807 of bank $FF ($1FF807). If bit #7 of a byte is set when written to this port (all other bits or values do nothing), BRAM becomes unlocked and directly read/writable. Locking BRAM is done by port $1803 ($1FF803). Any read of this port will automatically lock BRAM bank.

 The only problem I could see, is that if the card was used in a system that already had BRAM hardware. You'd have to somehow try to detect for it.

I don't konw what to say.first I post this is not to  make the friends all of the world jealous.second :this card havn't been a perfect card.If I make the SF2 run oK,and perhaps can add save Bram in this card. this card can share with friends who felling worth collecting.

Please do share with friends, as I definitely feel it is worth collecting. 

I was just messing around earlier by the way, people like to joke around on this forum.

Everyone (sane) here thinks this is really cool, even if this is the only one that gets made. DIPs, wires...only a jackass would complain about that stuff. I'd rather flip DIPs that deal with floppies, or parallel ports, or junk Windows clients that randomly decide to communicate with with USB ports.

DIP SWITCHES KICK ASS.

Im all for flippin 9 bastards.  Im an ex Commodore and PC-XT user. 

Dip switch AHOY!!!!!!!!!!!!!!!

too bad we dont get to partake of this personal amusement.

Let us not forget that someone, somehow, somewhere, has to program this thing.  So, anyone making this from the inventor's instructions/schematic/pcb_layout (hopefully this stuff will be shared), still needs a way to program the flash, as well as the appropriate files with which to actually do the flashing!

And, if you bought it, you are limited to only those proggies that is contains  Of course, since it contains "all" of them (almost), that may not be such a problem.

Just foor for thought.

PS.  DIP switches are ok, but I hate to see the manual for all the possible combinations!

Are you looking for good faith donations or play testers? 

[Duo_R]

U designed a board just for fun? Oh come on...... hahaha

I cant wait to see it.

also, thats not enough derp switches for every PCE game.  9 dip switches? 512 combos.......... ITS NOT ENOUGH.

Theres more than 512 games!
