Max size sprite is 32*32

So to draw a 40*32 sprite you would use 2 sprites. 32*32 and 8*32.

I'm not very easy with bankswitching but i thought all games > 2Mo use bankswitching.

I have this idea since all games>2Mo i have opened have 2 proms and chip like 74ls139... for bankswithing?

If you're talking about Pier solar, i've already my classic edition :lol: To be clear, i want to do a 64meg rom by using a bankswitch beetween 2 * 27c322 prom. I've built a test cart but i have to burn my 2 * 27c322 every time to test on real hardware, that's why i wanted to find an easier way to te...

Does everdrive support 64Meg games?

This site says Super street fighter II is supported, (40Meg?)

Thanks for those usefull infos!

Thanks, i've just understood that :lol: EDIT : no, Phantasy star IV is 3Mo but have 2Mo and 1Mo eprom. SO we never really address @ 0x200001 for the game... this is a bankswitch... So i suppose i can't have 8Mo cart AND sram. Or i have to build cart with 2Mo eprom only and bankswitch every 2Mo... (n...

Chilly, your code is addressing sram @ 0x200001. I suppose wa can modify this? Exemple, Phantasy star IV is 3Mo, so i think sram is @0x300001 right? I would just have to modify rom header, and modify your code, then i can use 3Mo for the game and my save @ 0x300001 or more right? Moreover, with my 8...

I had seen for sram_disable(); I knew this was copy-paste since there is a "enable" in the sram_disable(); code :mrgreen: I've the same problem. some time i put letters in wrong order since my right hand is typing faster :lol: In all case, you really help me with this. However, i wanted to build a 6...

New : - i burned an eprom and put it on a i'm problably a spammer 97 pcb. it's working only if i modify wire to sram. Address decoder is commanded by pin B9 on cartridge connector. i cut this link and link B9 to A20 (pin 32) on eprom. Ok, it boot but there are several problems. first, save don't wor...

Ok, so save is working. In order to test my demo on real hardware, i burned it on eprom (27c322) and put it on a standard sram pcb (i'm problably a spammer) (i don't own flash cart) i usually use this pcb and it works everytime, but this time not. I suppose my pcb is wired to work with game 512 to 4...

Thanks all ! Bastien, i think it's possible, but yesterday, i tested this method and it seems it wasn't working. (cause i haven't %) In your code, register are preceded by % symbol. Indeed, the 2 methods seems to be working. I have add % and the compiler don't return me any error. However, this code...

I don't know wich compiler i'm using.

I follow the tuto on wiki in order to use SGDK with code blocks. Nothing more.

i'll try to add % in front of register name, i'll tell you the result

You're my god :shock: I've really have to learn asm... i've created a sram.s with your code, then, a sram.h with void... here is the result of compiling... sram.s|16|Error: syntax error -- statement `move.l 4(sp),d1' ignored| sram.s|17|Error: operands mismatch -- statement `add.l d1,d1' ignored| sra...

Ok, i think i've undertood.

i will use another way to store hi score.

Thanks

I've another problem with save: I use those command lines *(vu8*)0xA130F1 = 1; /* enable sram */ if (*(vu8*)(0x200001) != 250) { j=15; VDP_drawText("First time running Dance Impact", 3, 3); VDP_drawText("Reset memory", 3, 7); for(i=0; i<5000; i++) { VDP_drawText(".", j, 7); if (i==4990 && j<20) {j++...
