Blinky Posted December 12, 2023 Author Share Posted December 12, 2023 3 hours ago, Thomas Jentzsch said: One could dump twice and compare I' think the dumper is doing that already to detect bankswitched roms. Once it finds a 'stable' rom it will dump it. If not it would not dump it. The tricky part is when to decide when a dump is good or bad. The emulator has more resources to determine this and could report back to the dumper that it was a bad dump and request a new one but I'm not sure if it would improve things. In most cases it will be likely be a bad insert / dirty cart and user interaction is required for that. Quote Link to comment Share on other sites More sharing options...

When I had my logic analyzer hooked to the tx line I noticed the dumper sends EA every 3-4 seconds when there is no cart and when there is a cart it sends EE in about the same interval as long as the cart is inserted. I see them now... I used: hexdump -Cv /dev/ttyS0 & But hexdump prints out entire lines so only when it has received 16 bytes. if I only sent hex 95 one or two times it won't print anything. When I send hex 95 16 times the dumper's response (16 times EA or EE) is output by the hexdump command. So it looks like the dmenu.bin is requesting cart status from the dumper, the dumper sin't doing this automatically. Quote Link to comment Share on other sites More sharing options...

If not, what's usual here? It's the configured speed of the MCUs UART. It uses the standard 1 start bit, 8 databits, no parity and 1 stop bit. It's actual serial speed is slightly faster than 115200 but within tolerance (it may vary a bit because the dumpers MCU is clocked by an internal RC oscillator which clock speed varies slightly depending on voltage and temperature) 1 Quote Link to comment Share on other sites More sharing options...

If not, what's usual here? Asyncronous serial transmission usually have 10 bits. With parity 11 bits. Sometimes people want to use 2 stop bits instead of 1 which makes it 12 bits per character.

Once the Upgrade is available I could try to do it via the hub instead of direct connection. Others have to tell if there is a possibility for a hack to use controllers or usb sticks on the external port (or the internal) in the future.

+wavemotion Posted December 21, 2023 Share Posted December 21, 2023 On 11/21/2023 at 2:31 PM, Thomas Jentzsch said: How is the situation of 7800 emulators in general? Is the ProSystem frequently updated? And are there better alternatives? Sorry, I'm just starting my holiday and catching up on a ton of threads! My A7800DS emulator uses ProSystem as the base and it's been nothing short of frustrating to get the accuracy to a place where I'm happy. It took more than a year of tweaks to get things mostly right. Much of that happened when I stumbled upon the Wii port of the emulator which had some nice improvements and I spent some time asking some dumb (easy for me!) questions here on AA. Most of the improvements I made to the base ProSystem were related to more accurate Maria Cycles accounting and Cycle Stealing (which is now universally applied - the original ProSystem only selectively applied this) along with improved cart detection and banking handling. I also added the stable "illegal" opcodes which were not present in the version of ProSystem I started with. If ProSystem base is to be used going forward, I'd at least seek out the improvements done from the unofficial Wii port but hone in on the cycle accounting. In particular, this table was instrumental in getting my emulation much closer - and that last highlight is super important since almost every ProSystem-based emulator gets the 'no DMA penalty' wrong. 5 Quote Link to comment Share on other sites More sharing options...
