From the feedback from Chinese users, someone with an older SD card took about 18 seconds to load a 4MB game, and when he switched to SANDISK Red 32GB, it took less than 4 seconds.

Yeah but do you know why FW5 does not work on my card since my SD card is fast enough?

@EZ-Flash2 it is possible make an option for turn off the RTC like the Ez-Flash Omega in a near update?

Why would you want that?

I'm sure flash cart makers could make carts that use significantly less power, if they really tried to optimize it for efficiency at the hardware level. They shouldn't use more power than regular carts, or you're doing something wrong.

I don't think you get the point. RTC mostly uses the internal battery for power. It would run decades continuously on a couple of AA batteries.

Compared to OMEGA's solidly soldered battery, I don't think Junior's replaceable battery is a concern at all for its consumption.

That would be great Willi! I am a bit afraid of updating to the beta firmware, so an official and more refined firmware would be great! My best wishes to you and your country Willi
Refined? Good! But saving states and cheat support would be appreciated. Saludos a todos los chilenos.

Our RTC design prohibits writes to registers, which keeps all games from interfering with the RTC, but Prism requires writes to the RTC registers, which we need to evaluate further.

If you are not in desperate need of playing RTC games or a user of a particular batch of Gameboy Color, please stay with Firmware 4 and Kernel 1.04e!

The current beta version has both RC and SGB versions available for installation. These versions are for advanced users only and are not recommended for general users.
both version have known issue: if user does not have an enough fast speed SD card. it will halt in LOADING or OSINIT screen after upgrade.

If you don't have a high speed SD card and have inadvertently upgraded to FW5 and K105 RC and are stuck in the LOADING or OSINIT interface. send a private message to me, I will give you the recovery tool.

Having an eye on this and the current issues. I first wanted to get the Everdrive GB X7 but it's ridiculously expensive and used it's extremely hard to find for a reasonable price. If the Junior gets all the issues fixed and reaches the same compatibility of the X7 i will consider buying it.

Did anyone compare power usage original vs. X7 vs. Junior yet?

Emulators, when faced with this problem, keep each game's RTC state separately and handle the RTC through an offset. That way they can present a proper MBC3 RTC to the games while not changing the system time. Would you perhaps be able to do something similar?

That's software vs hardware

  • TwoSpikedHands @ TwoSpikedHands:
    yall im torn... ive been hacking away at tales of phantasia GBA (the USA version) and have so many documents of reverse engineering i've done
  • TwoSpikedHands @ TwoSpikedHands:
    I just found out that the EU version is better in literally every way, better sound quality, better lighting, and there's even a patch someone made to make the text look nicer
  • TwoSpikedHands @ TwoSpikedHands:
    Do I restart now using what i've learned on the EU version since it's a better overall experience? or do I continue with the US version since that is what ive been using, and if someone decides to play my hack, it would most likely be that version?
  • Sicklyboy @ Sicklyboy:
    @TwoSpikedHands, I'll preface this with the fact that I know nothing about the game, but, I think it depends on what your goals are. Are you trying to make a definitive version of the game? You may want to refocus your efforts on the EU version then. Or, are you trying to make a better US version? In which case, the only way to make a better US version is to keep on plugging away at that one ;)
  • Sicklyboy @ Sicklyboy:
    I'm not familiar with the technicalities of the differences between the two versions, but I'm wondering if at least some of those differences are things that you could port over to the US version in your patch without having to include copyrighted assets from the EU version
  • TwoSpikedHands @ TwoSpikedHands:
    @Sicklyboy I am wanting to fully change the game and bend it to my will lol. I would like to eventually have the ability to add more characters, enemies, even have a completely different story if i wanted. I already have the ability to change the tilemaps in the US version, so I can basically make my own map and warp to it in game - so I'm pretty far into it!
  • TwoSpikedHands @ TwoSpikedHands:
    I really would like to make a hack that I would enjoy playing, and maybe other people would too. swapping to the EU version would also mean my US friends could not legally play it
  • TwoSpikedHands @ TwoSpikedHands:
    I am definitely considering porting over some of the EU features without using the actual ROM itself, tbh that would probably be the best way to go about it... but i'm sad that the voice acting is so.... not good on the US version. May not be a way around that though
  • TwoSpikedHands @ TwoSpikedHands:
    I appreciate the insight!
  • The Real Jdbye @ The Real Jdbye:
    @TwoSpikedHands just switch, all the knowledge you learned still applies and most of the code and assets should be the same anyway
  • The Real Jdbye @ The Real Jdbye:
    and realistically they wouldn't

    be able to play it legally anyway since they need a ROM and they probably don't have the means to dump it themselves
  • The Real Jdbye @ The Real Jdbye:
    why the shit does the shitbox randomly insert newlines in my messages
  • Veho @ Veho:
    It does that when I edit a post.
  • Veho @ Veho:
    It inserts a newline in a random spot.
  • The Real Jdbye @ The Real Jdbye:
    never had that i don't think
  • Karma177 @ Karma177:
    do y'all think having an sd card that has a write speed of 700kb/s is a bad idea?
    trying to restore emunand rn but it's taking ages... (also when I finished the first time hekate decided to delete all my fucking files :wacko:)
  • The Real Jdbye @ The Real Jdbye:
    @Karma177 that sd card is 100% faulty so yes, its a bad idea
  • The Real Jdbye @ The Real Jdbye:
    even the slowest non-sdhc sd cards are a few MB/s
  • Karma177 @ Karma177:
    @The Real Jdbye it hasn't given me any error trying to write things on it so I don't really think it's faulty (pasted 40/50gb+ folders and no write errors)
    Karma177 @ Karma177: @The Real Jdbye it hasn't given me any error trying to write things on it so I don't really...
