Sorry for the delayed reply, been a bit sick the last few days. www.bennvenn.com/GB/BootLoader_Lite.GB is the standalone ROM. It still needs to be optimised to speed up some of the routines but works in its current state. I'll update and post on here when its done.

Hi Imaginary,

Sorry about the COM mystery, I'll write up a quick tutorial and include it in the setup.

The patched (I'm assuming you mean patched LSDJ ROM) .sav is a direct copy of what is on the cart and will work in BGB, or on another flash cart. It is not a ROM, but a save file so naturally it will fail a ROM checksum if you were to try and run it as a GB ROM.

When you download the .sav (128k) from your cart via the linker, put it in a folder with your original LSDJ ROM and rename the .sav file to match LSDJ's ROM name, except ending with .sav

When you launch BGB and load the LSDJ ROM, it will automatically load the .sav file too.

Yes, the stand alone ROM can be added to your EMS cart and works the same way as the linker utility in LSDJ. Or I can send you a Patched LSDJ to put on your EMS cart. I'll send them through when I get home today.

As for the COM port, if you go into control pannel, system, devices, you can go down to the COM port entry, expand it and you'll see my linker in there with the COM number that has been assigned to it. This number will change if you put it in another USB port which is important to note.

The AVR will happily run at 3.3v as will the logic in the FTDI, Use the 3.3v from the FTDI and add a switch/jumper to select 3.3/5v cart voltage. No passthrough required, just a $0.10 jumper. That is how my Reader/Writers have GBA and GB compatibility

As the construction of the teensy and the game port interface is well within the limits of the average DIY'er and hobbiest, what would be the general consensus of reproducing the cart PCB+ROM and selling these AT COST PRICE to those that paid for and never received their GenMDM?

I understand that the ROM is little-scales' and this could be considered infringing copyright - Morally I feel those that paid for the product (Including the ROM) are entitled to receive it, if not a refund. Clearly refund is not an option here.

These would only be available to the customers that can prove their original purchase, and as I said earlier strictly cost price. This is not to make me money, more of a charity from someone who has the time, experience, equipment and expertise to do this.

If you think this is a bad idea, please voice your opinion and this will be the first and last time I'll mention it.

Ball park figure is USD$5 per blank PCB ($9 if gold plating is required) and $6 for the two programmed Flash IC's. Shipping worldwide would be ~AUD$3.80

Once a hobby turns into a job it ruins all that makes it fun. The little profit he was making had less and less appeal as the workload increased until it reached a point where the money was not worth the time, and as others have pointed out, the stress/anxiety. That explains why he sold elsewhere at an inflated price and still maintains a social profile. And why he doesn't want to release the project to the public.
It's upsetting reading through the 80pages of the rise and fall of GenMDM. A very talented person and a loss to the community.
Just my interpretation of all this...

Thanks Jovius,

You can have up to 3 patched LSDJ's and the limitation really depends on the length and complexity of the songs as it does in any LSDJ cart. So yes, many songs on each LSDJ. Each of my patched LSDJ ROM's use 56Megabits out of the 256 so that will give you an idea of how many other ROM's you can get on there. Usually quite a lot!
