haha thank you!

This was one of the most detailed and well laid out tutorials I've ever seen. Great Job! Very informative.

I've been making pcbs for a while now using the XGecu Pro. This is a very good video. I learned a few things. Thanks for making this!

Another excellent video. I don’t own a Sega, so will not be making carts, but I watched the video because it brought back memories of a time when a lot of the products my employer manufactured were EPROM based. I spent many happy hours with a programmer. I loved the explanation of little and big endian.

I wish I'd watched this before making my own Gameboy cartridges. Much of the advice is relevant and similar. I know how it feels to not know if anything will work after all the effort and money put into the project. But I did it :)

Thank you so much, I'm planning dev a game that I wrote for mega drive and release on cartridge later and your video casted light into obscure issues!

I have less moral issues with burning my own reproduction cart for some title that scalpers have turned into 4 digit prices than emulating it. (Not that I haven't done that plenty over the decades, too) I usually emulate to try before I buy, and then only bootleg if the originals are insane. Now at least I am learning how to do it myself for my own use, never to sell to anyone. Finally learning how to program so I can make my own original games too.

Cheeseburgers as a metaphor for endianness. Now i've seen everything :-)

Good evening. I liked the video for being very explanatory. here in Brazil we don't have these explanations. If you can inform me. When recording the game on eprom, you must make some changes to the texts inside the room. Can you inform me how these changes are made, because I did not understand at the time you showed to use the endiam swap site, where can I download this program? Does this Endian swap program already make all the necessary modifications to be able to record the game on the eprom? Sorry for the doubts, because I can't speak English. Thank you.

I came across a used Repro of Musha that a local pop store was selling for 150, they opened up the cartridge and low and behold I saw an eprom with the visible microchip silicon. I've never seen that before so was curious and finally came across this. They luckily sold Musha to me for 19.99. I was actually impressed with the repro label and the fact they used a close to if not original sega cartridge, as it said Acclaim made in Mexico on back piece, and used real screws. Cool stuff, as I am not about to drop 300-500 on Musha, and didnt want a cheapie repro. Moreover, the Board the UV eprom mine has is only a handful of contacts on the board. I've not seen a board like that. Wonder what kind it is.

Imho, rare expensive game copies are more appealing, as it allows to have somewhat-of-a-physical-media. That's why I prefer repros to flashcarts, because of that possessive feeling. Some Aliexpress repros were pretty good, but you always need to be careful, because cheap repros of save-games are faulty

@KenjiUmino

i have purchased TMNT Hyperstone Heist in box on aliexpress a couple years ago - too bad i forgot the seller's name because the cartridge is nice quality for a repro - the originals feel a bit more solid but the repro cartridge shell has no rough edges or other signs of half-assed manufacturing. same goes for the case - the trained eye will instantly spot that it's a repro because the transparent foil that protects the box art inlay is a bit more on the glossy side than an original would be ... the price was also ok ... under 10 bucks shipped or so - and most important - the game works as it should and didn't fry my console ... i've heard horror stories now, what's more appealing? well, I just bought an everdrive and this kind of erases the NEED to buy any more physical copies ... now I might still buy physical copies when i WANT to. but i think i'd rather buy new releases or new-to-this-region releases ... you know ... proper translations of games from japan or korea that have not been released in US/EU before. ... and it would be cool to have things like the "240p test suite" on a cartridge as a tool to keep around the workbench when repairing or modding consoles and equippment. a very awesome thing would also be if someone would take SMS games that would have had FM sound on japanese consoles, stuff the game ROM and the FM sound chip into a cartridge so westerners can finally enjoy SMS games like phantasy star with FM sound instead of whatever terrible noise generator the US/EU SMS consoles were stuck with.

Is it possible to program an EEPROM in a FlashKit or can it only be done using an EEPROM programmer?

@RetroBuiltGames

2 жыл бұрын

you need an EEPROM programmer. The voltages need for EEPROM are typically higher than flash; so they are separate devices

I’ve heard the specific programmer doesn’t work on anything higher than Windows 7 32 bit. Is that true or is there something extra that I’d have to do to be able to get it working on my windows 10 computer?

I wonder if there are some developers who develop cartridges using microcontroller, such as rp2040. Using this chip to increase the data memory capacity, save data and reduce the production cost.

In a perfect world SEGA would still manufacture and sell Mega Drive consoles, games, controllers etc. As well as the Master System, Saturn and Dreamcast. There wouldn't be any downsides to it because they would be so cheap to produce now and they could sell them with the original/reasonable prices. All they would have to do is manufacture what's selling. Unfortunately we live in a shitty world of licensing issues and CEOs who don't get retro gaming and game preservation.
