One pcb I'm going to try and put header pins on it to mount it around the cpu and the ppu1 and it will have all of the resistors, transistors, status leds, a couple switches and a connector for a flat ribbon cable on it. I'm going to try to split the pcb into 2 pcb's. I have some more pcb components on the way from China as soon as these come in(about 2 weeks) I'll be able to see if I'll be able make the upgrade that I would like to do. Rules let me know and it wont happen again and I'll delete the Project #2 post. Hopefully it was/is ok for me to talk about this chip here because it could be a game changer for future snes rom hacks. Which is, mega man x with sa-1, 128kb vram and a new engine to have game play like super metroid. If I can get the sa-1 hack completed it would set me up for a project that will blow all other projects that I have worked on away, Here is my mod chip installed on the snes motherboard: I was trying to get analog to get their super nt to support the extra vram but Iĭidn't have any luck probably because nothing uses the extra vram yet. To try and get 128kb of vram to work on the snes. As far as all my searching online I am the only person The extra vram but I need to write a editor from scratch to be able to use it. I already have a mmx v1.1 rom that fully supports I would be willing to modify the game that uses their editor to use the 128kb of vram. If anyone has a fully working level editor for a snes game and would like to add this feature to their editor I do have a few mod chips that Im willing to give away for free to people that have the skills and want to create hacks Im not interested in making any money off of the mod chip it will be fully open source for anyone to make it if Im getting ready to create a updated version of the super v-power mod chip and when its finished I'll uploadĪll of my schematics. The entire pcb I designed myself andĬreated in eagle cad. Holes to mount the pcb to the snes and he helped me in how/who to send the pcb to to get made. Qwertymodo was a really big help in showing me how to create the castellated The link to the debugger is on that 1st page. I also modified a snes debugger to show the extra vram in the vram viewer so there is a debugger that's supports the extra Byuu's forum is gone but it has been completely archived of the mod chip stuff is at the end of that page but you can see how it ended up getting made from reading everything from theīeginning. Up creating this mod chip on byuu's forum. I did not figure out the ppu can use the extra vram and I'm not really sure whoĭid but byuu made higan v1.00 and up capable of using the extra vram because he said it should be possible. The snes has 64kb of vram but the ppu is capable of using 128kb of vram.Ĭreating this mod chip kind of just fell in my lap. This mod chip is for adding extra vram to the snes. Project #2 New snes mod chip called Super V-Power! (v = vram) (100% working but could still be improved) I hope everyone enjoys the fast rom patch and the extra difficulties. I have no clue how long this is going to take but I chose gradius 3 for this because it is a small rom. I plan on having the snes cpu live in wram so the cpu's don't collide so I can get the full When I complete the wram to bw-ram change I'll start working on getting The sa-1 chip to work properly, this is near complete. I have been gradually changing the assembly code to store all wram data into bw-ram for I do have a gradius 3 rom that is updated to use the sa-1 chip but itĭoes not load gradius 3's assembly yet. Of the slowdowns so I have been learning about the sa-1 chip. I also want to addĪ new system for calculating your score after each boss kind of similar to super punch out. My main goal for gradius 3 is to remove all slowdown, add sram and make it feel like a competition cart. I really need someone to try and beat the hardest level to see if there are any bugs in the gameplay. The lastdual helped me with this patch by checking for bugs that I might have missed. Normal, hard and arcade are slightly easier.Įlite difficulty is the same as the original arcade difficulty but master, expert, and pro are gradually harder with pro as the There are 4 new difficulties which are elite, master, expert and pro. I also added extra difficulties that you can unlock by holding L, R, Y, and B buttons at the same time when you go into the There is definitely a noticeableĪmount of decreased slowdowns but it still doesn't remove all slowdowns. To be changed to fast rom locations but it shouldn't really affect the speed much. All assembly is complete there is just some data that still needs I have a near complete Gradius 3 fast rom. Project #1 Gradius 3 (fast rom about 99% complete, sram support work in progress) I currently have 2 important projects that need to be finished and released.
