How to load gecko codes in Riivolution

[PhilZockt]

So what I mean is I wanna have the option to activate and deactivate multiple Gecko codes. 

Code:

<option name="Cheats Codes">
                <choice name="Enabled">
                    <patch id="ocarinabase_gxdraw" />
                </choice>
            </option>
            <option name="speedometer">
                <choice name="Enabled">
                    <patch id="speedometer" />
                </choice>
            </option>
            <option name="disableluma">
                <choice name="Enabled">
                    <patch id="disableluma" />
                </choice>

It would be something like this. I modified it so its always using the gxdraw thing. But the problem is when I try something like this it wont work. It will only work with one Geckocode. Here is what I tried:

Code:

<patch id="speedometer">
        <memory offset="0x00001CDE" value="8000" />
        <memory offset="0x00001CE2" value="28B8" />
        <memory offset="0x00001F5A" value="8000" />
        <memory offset="0x00001F5E" value="28B8" />
        <memory valuefile="/codes/speedometer.gct" offset="0x800028B8" />
    </patch>
    <patch id="disableluma">
        <memory offset="0x00001CDE" value="8000" />
        <memory offset="0x00001CE2" value="28B8" />
        <memory offset="0x00001F5A" value="8000" />
        <memory offset="0x00001F5E" value="28B8" />
        <memory valuefile="/codes/disableluma.gct" offset="0x800028B8" />
    </patch>

And I think the reason for it is because the offset or something. I really do not know what im doing so I hope someone can help me .
