Current Problem PowerPak Games
The PowerPak has the potential to run any commercially NES game/ROM, and runs about 99% of them perfectly (I am not including Famicom here). Testing the ROMs with the latest combination of the PowerPak (Boot ROM 1.11, Mapper Pak 1.30 & Resistor Fix), here are some of my results.
I have only tested NES and a few Famicom (Disk) Games
Dirty Harry - The War Against Drugs (U) [!p].nes
Paperboy (U) [!].nes
No input recognized from NES controller. The ROM Paperboy (U) [f1].nes works fine.
Karnov (U) [!].nes
Severe background graphical glitching.
Bandit Kings of Ancient China (U) [!p].nes
Castlevania III - Dracula's Curse (U) [!].nes
Gemfire (U) [!].nes
Laser Invasion (U) [!].nes
Nobunaga's Ambition 2 (U) [!p].nes
Romance of The Three Kingdoms II (U) [!].nes
Uncharted Waters (U) [!].nes
MMC5 is not fully implemented, shows a black screen.
Batman - Return of the Joker (U) [!].nes
Shows just a solid grey screen. Worked (mostly) with Boot ROM 1.00 and Mappers 1.00.
Hot Slot (Unl).nes
Severe graphical glitches past title screen.
Peek-A-Boo Poker (Unl) [!].nes
Severe graphical glitches in female full-screen portraits.
Metroid v1.01 (1986)(Nintendo).fds - Metroid v1.02 (1986)(Nintendo).fds
Any version of Metroid for the fds will either refuse to load a game, or will load to a severely glitched screen, with Samus unable to move. The graphics glitches start to show themselves when it asks the player to set side B.
Interestingly, Low-G-Man did not display any sound glitches at all during the first boss battle. Both Punch-Outs!! worked without glitches, as did the rest of the FDS games I tried. Games like Alien Syndrome and Death Race worked fine as far as I could tell. Games that Nestopia assigns Mapper 206 also worked with the exception of Karnov.
In evert case, I used NTSC versions of the games, as that is my region. All ROMs were from the GoodNES 3.14 set.

How 256? I thought the maximum CHR length was 255 pages, and value 0 represented something like CPROM but with 8 KiB CHR RAM switching instead of 4 KiB.Dwedit wrote:Official CNROM games may have a 4 page limit, but iNES Rom files using Mapper #3 still expect up to 256 pages.
As I understand it, the difference between official CNROM and clone boards is as follows:
CNROM
- runs CPU D0-D1 and D4-D5 to 74HC161 inputs D0-D1 and D2-D3
- uses Q0-Q1 from the 161 as the bank number
- may run Q2-Q3 through diodes as a copy protection measure
- run CPU D0-D3 through the 161
- use Q0-Q3 as the bank number
I hacked both Paperboy and Dirty Harry at some point to fix them. Basically some issue with left over value on the bus or something to that effect is expected or not and the opposite happens causing the game which expects the same situation as the original board to occur to believe no buttons are pushed. I do believe this problem was supposed to have been fixed.
MMC5 is known to be unsupported so far. Would be nice if it worked atleast partially.
Metroid on FDS worked for me at some point. Never had any problem as you describe.

Could you post an IPS-type patch file for each game?MottZilla wrote:I hacked both Paperboy and Dirty Harry at some point to fix them.

As for Metroid, I get this with half of the images out there:

The other half I get a horribly garbled Brinstar starting screen and I can't move Samus around anywhere.
I did not test extensively, but I do not experience anything like that on the PowerPak. The small graphics glitches haven't really affected gameplay, but I can also confirm they don't exist with a real Crystalis game pak. [/code]crade wrote: I just threw the powerpak to test again.. It's the shops where the early more serious glitches happen... you cannot tell what is for sale in the shops due to graphical glitches. Same dump works correctly in nestopia. I'm only on boot 111 and mapper pak 1.2 at the moment though
